A MEX file is a type of computer file that provides an interface between MATLAB or Octave and functions written in C, C++ or Fortran.It stands for "MATLAB executable". When compiled, MEX files are dynamically loaded and allow external functions to be invoked from within MATLAB or Octave as if they were built-in functions.
MATLAB can call functions and subroutines written in the programming languages C or Fortran. [49] A wrapper function is created allowing MATLAB data types to be passed and returned. MEX files (MATLAB executables) are the dynamically loadable object files created by compiling such functions.
A MEX interface mexCGNS also exists for calling the CGNS API in high-level programming languages MATLAB and GNU Octave. Object oriented interface CGNS++ and Python module pyCGNS exist. The principal target of CGNS is data normally associated with compressible viscous flow (i.e., the Navier-Stokes equations ), but the standard is also applicable ...

S-Functions are used to specify a computer language description of a dynamic system. They are compiled as MEX-files that are dynamically linked into MATLAB when needed. S-Functions use a calling syntax that interacts with Simulink’s equation solvers.
Octave programs consist of a list of function calls or a script. The syntax is matrix-based and provides various functions for matrix operations. It supports various data structures and allows object-oriented programming. [26] Its syntax is very similar to MATLAB, and careful programming of a script will allow it to run on both Octave and ...
For n = 5 stones, the nimbers of the successor states of 2, 3, and 4 stones are the nimbers 2, 3, and 0 (as we just calculated); the mex of the set of nimbers {0, 2, 3} is the nimber 1, so starting with 5 stones in this game is a win for the first player. See nimbers for more details on the meaning of nimber values.
Place it a file example_mex.c, and compile it as: mex example_mex.c (make sure to run mex -setup at least once before). Finally run the new MEX-file in MATLAB as any usual function: Finally run the new MEX-file in MATLAB as any usual function:
