C/C++ Source Files

Write C/C++ functions using MATLAB® API libraries

A MEX-file lets you call a C function from MATLAB. To create a C/C++ MEX-file, you need:

For information about writing Fortran MEX-files, see Fortran Source Files.



MEX-files are not appropriate for all applications. MATLAB is a high-productivity environment whose specialty is eliminating time-consuming, low-level programming in compiled languages like C or C++. In general, do your programming in MATLAB. Do not use MEX-files unless your application requires it.
