Technical Questions of Matlab

There are a few technical questions that need to be known while working with Matlab:

Q1. Difference between M-file and MEX files.

Answer:

M-file: It’s a plain ASCII text, which gets interpreted at the run-time. These are basically like subprograms stored in a text file with .m extension and hence known as M-files. While dealing with Matlab development, most of the scenario Matlab is used.

MEX file: These are C and C++ files that are linked directly to Matlab at the time of run time. MEX files have the capacity to crash the MATLAB applications, so that needs to be handled carefully.

Q2. Explain Interpolation and Extrapolation in Matlab along with their types?

Answer:

Interpolation & Extrapolation are of two types:

Linear Interpolation and Extrapolation

Quadratic Interpolation and Extrapolation

Q3. What is Xmath-Matlab? Mention the Xmath features?

Debugging tools with GUI features

Libraries that are C and LNX C language compatible

Scripting language with OOP features

Q4. How to change/modify the Matlab path?

Answer:

One can use: use the PathTool GUI to modify the Matlab path. Add path directories from the command line and then add the path torc in order to write the current path back to ‘pathdef.m.’ In case one doesn’t have permission to write for ‘pathdef.m’ then paths can be written into a different file, you can execute from your ‘startup.m.’

Q5. How polynomials can be represented in MatLab?

Answer:

In Matlab, a polynomial is denoted by a vector. One needs to enter the coefficient of the polynomial into the vector in descending order and hence polynomial can be created.

The Concept Of Applied Ethics And Business

Ethics define how people should behave in certain situations. There is no right or wrong when it comes to ethics because it is an individual’s judgment. In simple terms, the majority considers ethics to be good. “Applied ethics” in ethics means the practical aspect of ethics. What would be the practical solution in the given scenario, not the ideal ethical answer that an individual might give without taking the situations and emotions into consideration?

In this article, we will be diving deep into the concept of applied business ethics, what are the benefits of applied business ethics for firms, and how certain companies are practicing it.

Applied Business Ethics

Applied Business Ethics asks companies to find practical and ethical solutions that will help the company promote human welfare along with its own. It is a method that ensures that the company is growing with the community. Applied business ethics can also be divided into three categories −

Applied ethical dilemmas at the individual level This deals with the ethical dilemmas that the employees of the organization or its leadership team might face while working for the organization and ensuring its success. There are going to be situations that demand the individual go a little out of their way to ensure that their work has been done, or else they would have to restart the process. In these scenarios, individuals should weigh the pros and cons of the same and try to make an ethical business decision. For example, a salesperson might face ethical dilemmas like

Should I inform the consumers about the negatives of the product?

Should I correct the consumer while he is making wrong assumptions?

Am I hiding certain crucial information that will lead to a loss for the consumer or a sour post-consumption experience? And others.

Applied business ethics at the business or organizational level − This refers to the ethics that a company wants to imbibe among its working culture and the people that are working with it. What the company thinks is right or wrong as a whole Employees can always refer to these ethics or values and use them as a guide in times of turmoil. The organizational level of applied business ethics helps the company and its members understand or address questions like

Is this how we should be achieving our goals?

Is this how we should be responding to our clients and their needs?

Is this how we should be treating your employees?

Applied business ethics at the community level − This helps us understand how businesses and their workings can influence the society that we live in. Businesses influence the laws, rules, regulations, environmental characteristics, and others of a community. Businesses can ask themselves questions to ensure that they are ethical in the community setting as well, and some of them are −

Am I giving back to society what I am taking from it?

Am I helping society in its drive toward a sustainable future? and others.

Instances to better explain the concept of applied business ethics

Samsung, Apple, and H&M These are prominent brands in the industry of technology as well as clothing. They are known to provide consumers with excellent-quality products at somewhat reasonable rates. All of the companies mentioned above now have manufacturing plants in developing countries. In this sense, they are producing high-quality products under their brand names but are using the land, people, and infrastructure of developing countries. Now companies are doing this because of the low cost of living in developing

countries. For example, if these companies produced the goods in their home countries, they would have to hire laborers. These laborers will cost the company approximately $12 per hour, but the same company can hire an employee in India, China, Bangladesh, or elsewhere for the same work at $1.25. So now the question is whether the company is fair. The company knows the actual wage rate in their country but provides labor to developing countries at a much lower rate, thereby kind of exploiting them. Now, adding another point to the discussion, what if the average wage rate in a particular developing country is $1 for the same manual labor done? Is the company now doing right by providing the laborers with $1.25? And if yes, then is it just because it is something that is above the standard of the country?

Bluffing on the negotiation table − There are scenarios in which companies bluff with clients or other clients to crack a deal. Though bluffing may appear unethical at first, it is perfectly acceptable in the poker game, and will be bluffing not be acceptable when the company is doing it to ensure that they are paid according to market value and not exploited?

Benefits of Ethics in Business

Being ethically right may cost the company money, opportunities, and clients. It is difficult to succeed in a corrupt world, but an ethically strong company will have the following pillar benefits −

It affects the bottom line − An ethically strong company would not have to bear the cost of the legal fees and doubts from the consumer’s end. In a survey, it was found that half of the consumers in the United States market will not purchase goods from companies that they perceive as unethical, and three out of every 10 consumers will express support for companies on social media that are ethical.

Drives employee behavior − Employees will be more ethical in their work if they see the organization doing the same. The way that the organization performs drives the behavior of employees.

Designs the organization’s working − With automation and artificial intelligence coming into place, it has become easier for businesses to detect unethical behavior. With the world moving toward hybrid, it has also become essential for companies to ensure that they have an ethical working space and ethical employees to minimize the chance and effects of losses because of ethical issues.

Applied Business Ethics helps companies reach the middle ground between the ideal scenario that we do not have and the corrupted ground that we breed in. It provides the company with solutions so that they are not defeated by competitors and can continue to be a prosperous and happy place to work. Companies have to start understanding and investing in business ethics to enjoy the delicious fruits of success in the long run.

Is Python Better Than Matlab?

Python code is typically more concise and readable than Matlab code.

There are various reasons for this, including −

In contrast to Matlab, which uses end statements as closures, Python determines the scope of a block based on its indentation (i.e., to signify the end of a block). Because of this, Python programmers are compelled to indent code blocks, which is typically a good practice. And no Python programmer ever wastes time searching for a missing end statement, in contrast to most other programming languages.

Almost all programming languages, with the exception of Matlab, utilize square brackets for indexing and parentheses for function and method calls. This includes Python. Both times, Matlab uses parentheses. Square brackets are essential for readability while indexing in Python, and they also make life simpler for programmers who need to work with many languages. Matlab code can be challenging to understand and is frequently the source of problems due to the use of parentheses for indexing and function calls.

Python, like almost every other programming language except Matlab, uses zero-based indexing.

Consider x as a one− dimensional array as an illustration. Python/NumPy uses x[0] as the first element, not x[1]. Matlab’s one-based indexing compels implementers to translate the indexes, which is troublesome and a source of mistakes because nearly every signal processing technique in the literature uses summations with indices starting at zero.

Python has great dictionaries’ support (hashes).

Except that the index (key) is not restricted to an integer, hashes are comparable to arrays. While coding a compiler or interpreter, a dictionary is a natural and incredibly effective way to create a symbol table. It is impossible to highlight the significance and value of dictionaries in engineering and scientific programming. However, Matlab imposes the pointless requirement that all keys be of the same type. Matlab does offer dictionaries, sometimes known as hash maps.

Python’s object-oriented programming (OOP) is simple and efficient.

Python’s object-oriented programming (OOP) is straightforward and elegant while yet offering C++− like capability and adaptability. Matlab’s object-oriented programming approach is challenging and too complicated. Here is an illustration from the official Matlab documentation −

The properties, methods, and events specified by the declared superclasses are all passed down to a subclass when it is derived from several classes. If a property, method, or event is defined by more than one superclass under the same name, all of the definitions must be resolved clearly. One of the following requirements must be met if two or more superclasses declare the same property under the same name −

The SetAccess and GetAccess attributes must both be set to private for all, or all but one, of the properties.

The attributes have the same definition across all superclasses (for example, when all superclasses inherited the property from a common base class).

Have you understood that? It is also hard to keep different iterations of the same class without changing the Matlab path since a Matlab class must be specified in a separate class definition file.

Python is free and open.

Python is open source, so it’s always possible to look inside to discover how things are done. On the other hand, Matlab is mostly closed-source and proprietary, and in certain situations, even the algorithms are proprietary (Simulink, a simulation toolbox for Matlab, contains a proprietary scheduling algorithm).

Each Matlab toolbox must be purchased separately, and Matlab licenses are rather costly. On the other hand, Python is open-source and free. It might be challenging to create a Python build that includes a good selection of libraries, but there are high-quality distributions that come with NumPy, SciPy, IPython (an interactive shell), matplotlib, and many other crucial libraries. Two really helpful freebies are as follows −

Enthought Canopy Distribution

Anaconda Python Distribution from Continuum Analytics

In another sense, the Python community is open. There is a lively, constructive public discussion on virtually every element of Python, and anybody who wants to participate may contribute their ideas.

Any number of functions can be bundled in a single file (module)

The MATLAB program files can include code for a variety of tasks, according to MathWorks. The main function, which is the first function in the file, is accessible from the command line and is visible to functions in other files. Local functions are extra operations performed by the file. Only other functions in the same file can see local functions.

Developers working on complicated Matlab− based projects are typically overwhelmed by a great number of little files since local functions are only accessible within the file in which they were written.

The import Statement of Python

The import statement used in Python is not present in Matlab. (Matlab searches the Matlab path, a list of directories, to resolve references to functions that are neither built-in nor provided inside the same file.) When a Matlab source code file’s name and the file’s primary (beginning) function have different names, the file name takes precedence over the function name that appears in the code. Due to these two design flaws, it is impossible to create several iterations of a single function without giving them unique names or by often changing the Matlab route. The placement of these files is critical and must be consistent with the Matlab path when breaking up a big Matlab program into numerous files.

After a shared library upgrade, there are three possibilities −

To “lock step” all developers into upgrading to the newest version.

The Matlab routes of users of the new (or old) version must be modified. (This presents a problem if the same person utilizes both the old and new libraries simultaneously in different applications.)

Users of one version modify their code in accordance with the other versions’ different names, which are given.

Python enables you to organize classes and functions into modules and packages, and any name conflicts are resolved using the name of the module or package. Python’s import statement gives programmers complete control over which components are used.

Python provides more options for graphics packages and tools

High−quality non−interactive 2−D and 3−D graphs produced by Matplotlib are more than enough for the majority of engineering and scientific graphics. To produce output that is ready for publishing, Python and matplotlib require less adjusting than Matlab.

It is possible to create graphical user interfaces using Qt, Traits, and Wx. (Wx is progressively being phased out.)

Chaco has an API for making interactive graphs.

Will Xbox One S and Xbox One X be supported after Project Scarlett releases? Yes, according to Xbox’s Phil Spencer, older versions of Xbox will be supported as long as there are enough people using them.

Will Project Scarlett support existing Xbox accessories? Yes, Microsoft is planning to support existing Xbox One games as well as the controllers and accessories.

Key Elements In Quality Management System (Qms)

A quality management system (QMS) is a framework of an organization’s policies, processes, and procedures to ensure that its products or services meet the required quality standards. The goal of a QMS is to continuously improve the quality of products and services, leading to increased customer satisfaction and business success. Several key elements comprise a QMS, including a quality policy, quality objectives, quality procedures, and continuous improvement.

In addition to these elements, several tools and techniques can support a QMS, such as Six Sigma and lean manufacturing. Implementing a QMS requires a company-wide commitment to quality and the active participation of all employees in the continuous improvement process.

It also requires strong leadership to set the vision and direction for quality efforts and provide support and resources to meet quality goals. By effectively managing the quality of its products and services, an organization can increase customer satisfaction, improve business performance, and stay ahead of the competition.

What are the Key Elements of a Quality Management System (QMS)?

Quality Policy − The quality policy is a statement of the organization’s commitment to quality and its goals for quality improvement. It should be clear and concise and should be communicated to all employees.

Quality objectives are specific, measurable goals that an organization sets for improving the quality of its products or services. These objectives should be aligned with the organization’s overall business goals and regularly reviewed and updated.

Quality Manual − The quality manual is a document that outlines the organization’s quality policies and procedures. It should provide an overview of the QMS and detailed information on the processes and procedures used to ensure quality.

Quality Procedures − Quality procedures are the specific steps an organization follows to ensure that its products or services meet the required quality standards. These procedures should be documented and followed consistently to ensure quality is maintained.

Quality records provide evidence of the organization’s compliance with its quality policies and procedures. They may include records of quality inspections, test results, and customer feedback.

Quality Audits − Quality audits are periodic reviews of the organization’s QMS to ensure that it is effective and compliant with relevant standards and regulations. Audits may be conducted by internal or external auditors and may include both documented and verbal reviews.

Continuous Improvement − Continuous improvement is a key element of a QMS, as it involves identifying and implementing opportunities for improvement in the organization’s products, services, and processes. Continuous improvement may involve analyzing data, implementing changes based on findings, and involving all employees in the improvement process.

Customer Focus − A QMS should be centered around meeting the needs and expectations of customers. This involves understanding their requirements and continuously improving products and services to meet those needs.

In addition to the key elements of a quality management system (QMS), there are several other important considerations for organizations to keep in mind when implementing and maintaining a QMS. These include −

Standardization − An organization needs consistent policies, processes, and procedures to ensure that quality is consistently maintained. This may involve adopting industry standards or developing internal standards specific to the organization’s products and services.

Communication − Effective communication is crucial for the success of a QMS. This includes communication within the organization, as well as communication with customers and other stakeholders.

Training − Ensuring all employees are trained on the organization’s QMS is essential for its success. Training should cover the policies, procedures, and tools used to ensure quality, as well as the roles and responsibilities of each employee in the quality process.

Resource Allocation − Adequate resources must be allocated to support the QMS, including personnel, equipment, and financial resources. This may involve investing in new technologies or training programs to support quality efforts.

Risk Management − A QMS should include a risk management plan to identify and mitigate potential risks to the quality of products and services. This may involve conducting risk assessments, implementing controls to reduce risk, and monitoring and reviewing risks on an ongoing basis.

Performance Measurement − It is important to measure the performance of the QMS to ensure that it is effective and achieves its desired outcomes. This may involve gathering data on the performance of processes, identifying areas for improvement, and implementing changes based on findings.

Customer Feedback − Gathering and analyzing customer feedback is an important aspect of a QMS, as it helps identify areas for improvement and ensure that products and services meet customer needs. This may involve collecting customer feedback through surveys, focus groups, or other methods.

Conclusion

We may draw the conclusion that these eight components are essential to guaranteeing TQM’s success in a company and that the supervisor plays a significant role in fostering these components at work. Business entities cannot successfully adopt TQM without these components.

The explanation above makes it quite evident that TQM would be seriously flawed—in fact, it would be lacking—without the inclusion of integrity, ethics, and trust. The key to helping the organization build a TQM climate is training. Teamwork and leadership go hand in hand. The entire TQM process is hampered by a lack of communication between departments, managers, and employees.
