Excerpts from document:

MATLAB is a programming language and a computing environment that uses matrices as one of its basic data types. It is a commercial product developed and distributed by MathWorks. Because it is a high level language for numerical analysis, numerical code to be written very compactly. For example, suppose you have defined two matrices (more on how to do that presently) that you call A and B and you want to multiply them together to form a new matrix C. This is done with the code C=A*B;
