What is the .MEX File Extension?


.MEX File Extension Description:

The file extension .mex is used as an executable command by the MATLAB interactive environment and high level language, which can perform intensive computation quicker than more traditional development languages. The .mex file extension is also used by the application for Dynamic Link Subroutines in its Macintosh version. The application that generates the .mex file extension is a powerful engineering application, used in solving problems with the use of a toolbox that compiles its files into executable formats.

Scripts written in the language can be compiled and transformed to EXE file formats, with the functions being compiled to the .mex file extension, which have the equivalent of a DLL file format under the Microsoft Windows Operating System platform. The use of the DLL extension is only for the Windows environment, under other operating system platforms, the .mex file extension is retained.

Since .mex file extensions contain classes, functions and variables, which are loaded by the application, this allows for faster execution of the system. In creating files with the file extension .mex, MCC (the MATLAB C/C++ compiler) can be used which can also compile them to executables with either a DLL or EXE file format. FORTRAN or C subroutines can also be loaded by the application directly as if they are part of the program's built-in functions. MEX actually stands for MATLAB Executable, which generates the file extension .mex and uses an external interface to provide functions that allow data transfer and calling of MEX files in MATLAB.

Files with the .mex file extension are created mainly for calling large FORTRAN or C routines without rewriting them as M-Files, and for the speed of converting computation bottlenecks to more efficient codes. Every .mex file extension must have the following components present; mex.h (for C/C++ MEX), mexFunction (Subroutine in FORTRAN), mxArray, and API Functions.

The WordPerfect and Macro Express applications in relation to their macro command functionality also use the file extension .mex. WordPerfect uses the .mex file extension as an expound file for its macro editor, while Macro Express implements it for its macro utility for the Microsoft Windows Operating System platform. A macro is basically a series of actions and commands utilized to automate application tasks, which are regularly and repeatedly performed that allows for a more productive computer usage and less user strain.
