It is possible to compile C, C++, or Fortran code so that it is callable from Matlab. This kind of

program is called a Matlab Executable (MEX) external interface function, or more brie

y a \MEX-

function." MEX enables the high performance of C, C++, and Fortran while working within the

Matlab environment. We will discuss C/MEX functions, which also applies directly to C++/MEX.

Fortran/MEX is quite dierent and we do not discuss it here.
