MATLAB is a proprietary programming language developed by the software developing firm MathWorks. This high-level programming language is good at matrix manipulation, plotting of functions and data, the creation of user interfaces, and implementation of algorithms. Moreover, programmers find it convenient to use as it saves time to install and configure new libraries for various tasks. Furthermore, it is easy to code its programs as they are concise. Software programmers often say that 10-20 lines of C++ code could be replicated in 1-2 lines of MATLAB code. This feature also makes it easy to find out the errors and rectify them. Here we have discussed some real-life usage of this programming language:

Engineering new solutions

Engineering is a multidisciplinary subject that draws its concepts from mathematics too. In order to prove a result, engineers need to apply mathematical theories. For instance, before constructing a building, an architect needs to get an idea about how much load it can bear and what should be the best design in order to ensure its strength. Similarly, in case of developing a computer software, one needs to plan its data processing speed and error detection capacity. While in the past, engineers had to do all these mathematical calculations manually, now they have MATLAB to do them instantly.

Working with linear algebra

It may be hard to believe, but linear algebra is a part of the workplace. For instance, to know about the return on investment, you need to apply the theory of algebra. Moreover, it helps in stock estimation and cost management of a product. In linear algebra, data are estimated by using matrices and vectors, which is a time-consuming method. But with the help of MATLAB, it has become easy to handle equations of any complexity.

Performing numerical analysis

Numerical analysis is important for certain real-life applications, but in order to work effectively, one needs to draw the most probable data. For instance, astronomers do not know the exact distance between every two planets, and the measurements that they put forward in terms of light years is based on estimation.

Getting involved in science

MATLAB is used extensively by the scientific community to perform “what if” analysis on a new propagation. For example, it can help in finding the effectiveness of a drug to cure a disease. Similarly, it can be used in identifying the best ways to mitigate air pollution in a certain area.

Engaging mathematics

MATLAB makes it easy to engage with mathematics. You can use it to create new ways of using a theorem or retrieving a short-cut to a complex mathematical application. Moreover, it can also help in checking the answer to a mathematical problem.

Employing image processing

Image processing is a method to convert an image into digital form to retrieve its details and managing the pixels using mathematical values. With the help of MATLAB, we can now use this technique in various areas, such as disease treatment, forensic report generation, and disaster management. There are five purposes of image processing which include visualization, image sharpening and restoration, image retrieval, measurement of pattern, and image recognition.

Embracing computer programming

Before executing a program, computer scientists prefer to check the algorithm using the rich toolbox MATLAB so that the efficiency of the code could be determined. Therefore, it ensures the validation of the output and also enhances the productivity of the programmers. Well, verification is just one benefit out of many that MATLAB provides to the computer scientists. So, it is absolutely correct to say that computer science relies heavily on mathematics, and MATLAB certainly is of great use for implementing an algorithm.
