MATLAB is a commercial numerical computer algebra system

MATLAB is a commercial numerical computer algebra system developed by MathWorks, Inc. It is also a programming language. The core is focused on matrix algebra, but extensions (so called "packages", e.g. Simulink) add functionality. This tag should be used to mark questions regarding the use of MATLAB in an electronics and systems theory context, not the general usage itself.

Why is MATLAB used so much in industry when there's other software that can do a better job?

All the classes I'm taking require the projects to be done in MATLAB when there are times that C++ would be much better to use. One time the professor took three hours to find a transfer function when it would have taken two minutes tops in Maple or…
