mex -setup does not see a C++ compiler

Hello, I am having trouble getting mex -setup to recognize any of the C++ compilers I have installed (Microsoft Visual C++ Express, Intel Studio 2011).
>> mex -setup Please choose your compiler for building external interface (MEX) files:
Would you like mex to locate installed compilers [y]/n? y
Select a compiler:
[0] None
What do I need to do to remedy this issue? I am using Matlab R2009a, so I am not sure the "patches" I have read about will fix my problem. Perhaps it is something more basic? Any suggestions/advice you might provide would be greatly appreciated!

You are using R2009a, so consult its pages for compilers that were supported at the time of its release:
Visual C++ 2005 SP1 was the supported Microsoft tool chain for use with Intel C++/Fortran version 9.1 or 10.1. It sounds like the Intel and Microsoft you are trying to use all post-date the release of 2009a, sorry.

If you know the path to the compiler, you can say [no] to locate installed compilers and manually give the path.

It does not appear to be a supported compiler. See here.
Although it is fully possible you may be ok with that compiler in what you are doing in MATLAB, you may run into issues down the road.

Thanks for your response. I thought about that, but when I tried it, it seemed to insist I select from a menu (that includes none of the compilers I actually have installed). At each iteration I tried selecting none or even just selecting one of the provided defaults, but when asked for a path it rejected what I entered:
>> mex -setup Please choose your compiler for building external interface (MEX) files:

Select a compiler: [1] Intel C++ 9.1 (with Microsoft Visual C++ 2005 SP1 linker) [2] Intel Visual Fortran 10.1 (with Microsoft Visual C++ 2005 SP1 linker) [3] Intel Visual Fortran 9.1 (with Microsoft Visual C++ 2005 SP1 linker) [4] Microsoft Visual C++ 2005 SP1 [5] Microsoft Visual C++ 2008 Express [6] Microsoft Visual C++ 2008 SP1
[0] None
Compiler: C:\Program Files (x86)\Intel\Composer XE 2010 SP1 Please select from 0-6 Compiler: 0
mex: No compiler selected. No action taken.

Selecting none cancels the action, selecting another menu option brings this message:
The default location for Microsoft Visual C++ 2008 SP1 compilers is C:\Program Files (x86)\Microsoft Visual Studio 9.0, but that directory does not exist on this machine.
I am getting the sense that I am not adequately telling it where to look, but I unsure how/where to fix the problem.
Thanks again!
