Matlab 2013b Mex function can't make gcc 4.7 work

Problem: Mex function won't work - I'm using Ubuntu 13.04 and Matlab 2013b, and compatible gcc 4.7, so I don't need a different gcc version. Either gcc 4.7 is not installed correctly, or Matlab can't find it. Any solutions, please??!!

Error displays:

>> mex -setup

    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 /home/edward/.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 /home/edward/.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: /usr/local/MATLAB/R2013b/bin/mexopts.sh : 
    Template Options file for building MEX-files

0: Exit with no changes

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

mex LOAD_WGhrly2.c

    mex:  LOAD_WGhrly2.c  not a normal file or does not exist.

Unable to complete successfully.

Does the file LOAD_WGhrly2.c exist in the current working directory? The error message seems to suggest otherwise. Perhaps you can try running:

>> !ls LOAD_WGhrly2.c

Thanks, it appears that Matlab was trying to access a different folder, so I moved my files into that one rather than mess about with setting paths. Plus, I now know that you have to use the matlab terminal to 'cd' into the directory where the file is before you can mex it. Thanks.
