Default Options File on UNIX

The default MEX options file provided with MATLAB is located in <matlab>/

bin

. The mex script searches for an options file called mexopts.sh in the

following order:

•The current directory

•

$HOME/.matlab/R12

•<matlab>/bin

Override options file setting for variable <name>.

This option is equivalent to

<ENV_VAR>#<val>,

which temporarily sets the environment variable

<ENV_VAR> to <val> for the duration of the call to

mex. <val> can refer to another environment

variable by prepending the name of the variable

with a

$, e.g., COMPFLAGS#"$COMPFLAGS -myswitch".

(UNIX) Override options file setting for variable

<name>.

-O

Build an optimized executable.

-outdir <name>

Place all output files in directory <name>.

-output <name>

Create an executable named <name>. (An

appropriate executable extension is automatically

appended.)

-setup

Set up default options file. This switch should be the

only argument passed.

-U<name>

Undefine C preprocessor macro <name>.

-v

Verbose; print all compiler and linker settings.

-V4

Compile MATLAB 4-compatible MEX-file.
