>>mex -setup

    Using the 'mex -setup' command selects an options file that is
    placed in ~/.matlab/R12 and used by default for 'mex'. An options 
    file in the current working directory or specified on the command line 
    overrides the default options file in ~/.matlab/R12.

    Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.
 
    To override the default options file, use the 'mex -f' command
    (see 'mex -help' for more information).

The options files available for mex are:

  1: /afs/glue/software/matlab/6.1/bin/gccopts.sh : 
      Template Options file for building gcc MEX-files
 
  2: /afs/glue/software/matlab/6.1/bin/mexopts.sh : 
      Template Options file for building MEX-files via the system ANSI compiler
 

Enter the number of the options file to use as your default options file:

1
Overwrite /homes/dkedar/.matlab/R12/mexopts.sh ([y]/n)?

/afs/glue/software/matlab/6.1/bin/gccopts.sh is being copied to
