MatLab not recognising compilers on Ubuntu 12.10

At the end of the installation process I am told that I need compilers installed for MatLab compiler to work and given a link to the supported compilers. However, I have both gcc and g++ (gpp) installed with the latest versions. If I click "next" and activate MatLab anyway, it does not show up as a program anywhere on my computer. Is there any way to fix this?

What do you mean by "it does not show up as a program anywhere on my computer"? Can you try compiling a program and tell me if its successful?

You can compile a program using >> mex prog_name.c

Do you mean the MATLAB program (or its icons) don't show up anywhere on your computer after the installation program has totally finished?

I think the compiler message is a red herring here.

Typically, the installer will put a link at /usr/local/bin/matlab; here is what the installer did on my Ubuntu system:

 local@ubuntu:~$ ls -l /usr/local/bin/matlab
 lrwxrwxrwx 1 root root 35 Feb 10 22:28 /usr/local/bin/matlab -> /usr/local/MATLAB/R2013b/bin/matlab

So, assuming /usr/local/bin is on your search path, "matlab" from a Terminal window should be sufficent to start MATLAB. If you find a Launcher icon more convenient, you can create one by right-clicking on the MATLAB icon that appears after you start it and selecting "Lock to Launcher".
