What Is MATLAB?

MATLAB (short for Matrix Laboratory) is a high-level programming language and numerical computing environment developed by MathWorks. It is designed for mathematical computation, algorithm development, data analysis, simulation, visualization, and engineering applications.

Unlike many general-purpose programming languages, MATLAB is built around matrix and array operations. Since matrices are fundamental in mathematics, engineering, and scientific computing, many calculations that require dozens of lines of code in other languages can often be completed with just a few lines in MATLAB.
