Summary
Rationale: A numerical computing environmentWhat is Matlab
MATLAB (matrix laboratory) is a multi-paradigm numerical computingenvironment and fourth-generation programming language. A proprietaryprogramming language developed by MathWorks, MATLAB allows:
matrix manipulationsplotting of functions and dataimplementation of algorithmscreation of user interfacesinterfacing with programs written in other languages, including
CC++C#JavaFortranPython

Summary
Rationale: A numerical computing environmentExpanding Matlab
Although MATLAB is intended primarily for numerical computingan optional toolbox uses the MuPAD symbolic engine, allowing access tosymbolic computing abilitiesan additional package, Simulink, adds graphical multi-domain simulation andmodel-based design for dynamic and embedded systems≈ 100 additional toolboxes are available

A Un-Irrelevant ConsiderationDo we Save Money?
As the mean cost of each toolbox is ≈ 2 ke, the current (nov. 2016) Matlabtotal computing potential would cost 2 × 116 × 39 ≈ 9 Me.The Jan 2016 MEA agreement with Mathworks Italy gives us such apotential at ≈ 50 ke
