mex setup on Mac OS x (10.7.5) and matlab R2013b-64bit

Hi everybody,

I am trying to install MAXDET optimization software which is a c based software and I need matlab interface such as mex compiler to use this package. I do not know how I should proceed to setup mex compiler for my 64bit R2013b matlab on mac system. When I type mex -setup in matlab command I get this:

    Options files control which compiler to use, the compiler and link command
    options, and the runtime libraries to link against.

    Using the 'mexsh -setup' command selects an options file that is
    placed in /Users/localadmin/.matlab/R2013b and used by default for 'mexsh'. An options 
    file in the current working directory or specified on the command line 
    overrides the default options file in /Users/localadmin/.matlab/R2013b.

    To override the default options file, use the 'mexsh -f' command
    (see 'mexsh -help' for more information).

    The options files available for mexsh are:

1: /Applications/MATLAB/MATLAB_R2013b.app/bin/mexopts.sh : 
    Template Options file for building MEX-files

0: Exit with no changes

Enter the number of the compiler (0-1):

How do I proceed? I looked at the similar posts but I could not figure out how it works. I have Xcode 4.6.3 installed on my laptop with command line toolbox installed and when I type gcc -v on command line I get this:

"Using built-in specs. Target: i686-apple-darwin11 Configured with: /private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/src/configure --disable-checking --enable-werror --prefix=/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2 --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-prefix=llvm- --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-darwin11 --enable-llvm=/private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/dst-llvmCore/Developer/usr/local --program-prefix=i686-apple-darwin11- --host=x86_64-apple-darwin11 --target=i686-apple-darwin11 --with-gxx-include-dir=/usr/include/c++/4.2.1 Thread model: posix gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)"

So I guess my c compiler is properly installed.

Thanks for your help, I desperately need to make this work!

What messages are you getting that suggest to you that your mex is not set up properly?
