MEX file
Encyclopedia
MEX stands for MATLAB Executable. A MEX file (also written as MEX-file) provides an interface
between MATLAB
and subroutines written in C
, C++
or Fortran
.
When compiled, MEX files are dynamically loaded and allow non-MATLAB code to be invoked from within
MATLAB as if it was a built-in function. To support the development of MEX files, MATLAB offers
external interface functions that facilitate the transfer of data between MEX files and MATLAB.

MATLAB
MATLAB is a numerical computing environment and fourth-generation programming language. Developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages,...

C++
C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...
