You can call your own C, C++, or Fortran subroutines from the MATLAB® command line as if they were built-in functions. These programs, called binary MEX-files, are dynamically linked subroutines that the MATLAB interpreter loads and executes. The MEX-file contains only one function or subroutine, and its name is the MEX-file name. To call a MEX-file, use the name of the file, without the file extension. For information about using a MEX-file that someone else created, see Call MEX-File Functions. The term mex stands for ”MATLAB executable” and has different meanings, as shown in the following table.
