What is MATLAB?

MATLAB stands for matrix laboratory and was used to access LINPACK projects. MATLAB is a high-level technical programming language which helps with simulations and analysis. It combines analysis, computation, programming and visualization. This helps it create a simple environment for solving problems. This easy-to-use environment helps engineers solve high-level problems. It also makes it easier for them to express problems in a mathematical form. The most common uses of MATLAB include computation, development, prototyping and visualization. MATLAB is a scalar interactive programming language, unlike Fortran or C.

Parts of MATLAB Systems

  • MATLAB language- High-level matrix language containing statements, variables, data structures and OOP features. It facilitates both programmings in the small and large, allowing scalability.
  • Working environment- All the tools that a programmer uses while employing MATLAB. This includes functions that help in controlling variables and exporting of data. Also includes other tools such as ones used to develop and debug M files.
  • Graphics Handling- This helps with 2D and 3D data visualisation and image processing. It also deals with low-level commands which help in customising how the graphics look.
  • Mathematical library- Vast collection of algorithms for mathematical computation. This includes everything from trigonometric functions to Bessel functions and Fourier transforms.
  • MATLAB API- Library that allows users to code in C and Fortran and use that on a MATLAB environment. It works as a computational engine that helps in dealing with M-files.

How does MATLAB make Work Easier?

A simple question that might pop into your head right now is, “Why should I learn MATLAB being a mechanical engineer?”. Well, the answer is simple. MATLAB is a flexible and useful computational tool that helps in creating efficient solutions. Most types of engineering are undergoing a massive transformation. Almost all fields are expanding into each other. This means that nowadays multidisciplinary skills are required to be successful. In such an environment knowing how to run and use MATLAB is a great advantage that can help you get places.

MATLAB allows you to code faster and more efficiently. The code is compiled using a Just-In-Time compiler. It is optimized with each operation distributed as per the computer’s capabilities. Furthermore, MATLAB runs algorithms alongside such operations, making the final execution much faster. When compared to Java, algorithm development occurs faster in MATLAB. The MATLAB IDE also has interactive applications for visualizing and computing data faster.

Advantages of MATLAB

  1. Fastest IDE when it comes to mathematical computation
  2. Best mathematical library for technical operations on various types of datasets
  3. Good support from an interactive community
  4. Enables multi-threading support which allows the parallel execution of algorithms
  5. Adaptive and efficient graphics system
  6. Great capability when it comes to data visualization as it allows image processing and graphing

Is MATLAB difficult to learn?

As with all other programming languages, MATLAB is easy enough if it clicks to you. However, unless you understand how the language works, you will not be able to use it to your advantage. Therefore, the best way to learn MATLAB is to figure things out by yourself by working on projects. Try to look up for theory online, via courses offered by qualified professionals. Follow their lectures and understand the basics. Then pick up a project in an area you like and enjoy working in, and try to incorporate MATLAB into it. Design algorithms for that problem and test out your program within this environment. Keep tweaking your program until it satisfies all your criteria and then moves on to more advanced programs. Take a look below at some great MATLAB courses you can use to learn MATLAB being a mechanical engineer.
