Welcome to mex -setup.  This utility will help you set up  
a default compiler.  For a list of supported compilers, see

  Warning: The MATLAB C and Fortran API has changed to support MATLAB 
           variables with more than 2^32-1 elements.  In the near future 
           you will be required to update your code to utilize the new 
           API. You can find more information about this at: 
           http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html  
           Building with the -largeArrayDims option enables the new API.
