Setting-up Matlab R2010a compiler

Salamo3alaykom,

If you're using Matlab R2010a on Win7, you're probably getting an issue with the C++ compiler using mex command.
So to overcome this issue you have to get a compatible compiler installed, you can check all the compatible C++ compilers here.
I had the Visual Studio 2008 installed and thenin the matlab command window I run the msbuild command to set-up the C/ C++ compiler to be used with MATLAB.
So, you shoulget something like this:

>> mbuild -setup
Please choose your compiler for building standalone MATLAB applications:

Would you like mbuild to locate installed compilers [y]/n? y

Select a compiler:
[1] Lcc-win32 C 2.4.1 in C:\MATLAB\R2010a\sys\lcc
[2] Microsoft Visual C++ 2008 SP1 in C:\Program Files\Microsoft Visual Studio 9.0

[0] None

Compiler: 2

Please verify your choices:

Compiler: Microsoft Visual C++ 2008 SP1 
Location: C:\Program Files\Microsoft Visual Studio 9.0

Are these correct [y]/n? y

Done . . . 

I hope that was helpful, and good luck with Matlab :D
