## @deftypefn  {} {} mex [-options] file @dots{}

## Compile source code written in C, C++, or Fortran, to a MEX file.
##
## @var{status} is the return status of the @code{mkoctfile} function.
##
## If the compilation fails, and the output argument is not requested,
## an error is raised.  If the programmer requests @var{status}, however,
## Octave will merely issue a warning and it is the programmer's responsibility
## to verify the command was successful.
##
## This is equivalent to @code{mkoctfile --mex [-options] file}.
