I am trying to to use mex but I cannot make it work.
I have Matlab 2013a installed in a Ubuntu 12.04 (64 bit). I also have gcc 4.6.3 insatalled.
No matter what I try wiht mex, but I always get the same error with no information:
>> mex
Error using mex (line 206)
Unable to complete successfully.
>> mex -setup
Error using mex (line 206)
Unable to complete successfully.
>> mex test_function.cxx
Error using mex (line 206)
Unable to complete successfully.
Any ideas?

When you type ver on the command line, do you see the compiler listed?

Well then you need to purchase the MATLAB Compiler Toolbox.

that makes sense hehe.
I didn't know it was a separate toolbox.
Thanks

Nope, that didn't work. However do I need the compiler library to use mex (I don't want to compile an .m file)?
I have even reinstalled but it still won't work. For now I will just compile the cxx function somewhere else

No, you do not need MATLAB Compiler product to use the MEX function. If ">>mex -setup" is erroring out exactly the way you've mentioned above then that means your GCC may be wrongly installed on the system.
By the way, you need gcc 4.4.x, as gcc 4.6.3 is unsupported with R2013a. So first, install the correct version and make sure it's installed correctly by executing ">>!gcc --version" from inside MATLAB. If it shows the correct version then, try executing ">>mex -setup".
