compiling a Matlab file into 'c'

Hi all,

I have a code which is running really slow in Matlab (due to a long loop), so I thought I should run it in 'c' instead. However, when I enter
            mcc -B sharedlib:libmyfilename filename.m
I get the following warning:
*****************
You are using gcc version "4.1.2". The version currently supported with Matlab compiler is "4.3.4". For a list of currently supported compilers see: http://......
*****************

At the moment, I'm using the uni's Linux machine with Matlab 2011b. How can I upgrade gcc version and do I need administrative privilege?

Also my main running file refers to several other scripts within the directory. Would this be a problem in compiling? (as I read in help: "functionality that cannot be recalled directly from the command line will not compile"). I think this issue can be resolved by putting all the scripts in one file instead of referring to them (?).

Many thanks,
Emma

I solved the above issue. But, can someone please give me a hint on how to run a Matlab code in 'c' (Xcode)?

1st. step: Type in Matlab command line "mcc -B csharedlib:libmyfilename filename.m"
2nd step: ????
3rd step: ????

Thanks in advance.
PS: 'c' is totally alien to me -- so please bear with me.

If you need to generate C code from your MATLAB function, use MATLAB Coder.

http://www.mathworks.com/products/matlab-coder/?s_cid=global_nav

If you need to run your application on a machine that could run MATLAB but
on which MATLAB is not installed, you can use MATLAB Compiler.

http://www.mathworks.com/products/compiler/?s_cid=global_nav

The documentation for each of those products includes instructions on how to
use the products to create the C code or the deployable application.
