# Introduction to Matlab

Matlab or Matrix Laboratory is a high-level programming language consisting of an interactive environment mainly used for numeric computation, programming, and visualization. It has been developed by MathWorks. The basic functions of Matlab are plotting of functions and data, the creation of user interfaces, matrix manipulations. It also provides support for interfacing with other programming languages in C, C++, Fortran, and Java. Besides, it is also used to analyze data, create models and applications, and also develop algorithms. Along with all this, introduction to Matlab also provides numerous built-in functions for mathematical operations involving numerous calculations, performing numerical methods, generating plots, and a lot of other functions. Matlab also has a very good scope in the automotive domain using Rapid control Prototyping or RCP used extensively in medical, automotive, and aerospace domains.
