Specifying an Options File

You can use the -f option to specify an options file on either UNIX or Windows. To use the -f option, at the MATLAB prompt type

• mex filename -f <optionsfile>
  

and specify the name of the options file along with its pathname. The Options Files table, below, contains a list of the options files included with MATLAB.

There are several situations when it may be necessary to specify an options file every time you use the mex script. These include:

• (Windows and UNIX) You want to use a different compiler (and not use the -setup option), or you want to compile MAT or engine stand-alone programs.
• (UNIX) You do not want to use the system C compiler.

Preconfigured Options Files

MATLAB includes some preconfigured options files that you can use with particular compilers. The Options Files table lists the compilers whose options files are included with this release of MATLAB.
