What is MATLAB, its use and application in engineering?

MATLAB is a high-level programming language and interactive environment mostly used for numerical computation, data analysis, and visualization. With its many built-in tools and functions, MATLAB makes it simple to perform tasks like matrix manipulation, linear algebra, signal processing, image processing, and more. Engineers, scientists, researchers, and students are especially drawn to it because of the syntax's user-friendly design and resemblance to mathematical notation.

MATLAB's versatility makes it applicable to a large number of fields, like engineering, physics, finance, biology, and beyond. Engineers build simulations, control systems, and algorithms using MATLAB. Scientists perform complex system modelling, data visualization, and statistical analysis. It's also frequently used for creating user interfaces, interactive visualizations, and machine-learning models. MATLAB is still a helpful tool for solving a range of issues in engineering, science, and other fields due to its large function library and engaged user numbers.
