I have installed Visual C++ 2008 Express Edition with SP1 and Windows SDK 6.1. I was also able to locate my compiler (cl.exe) in C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin. According to the sitehttp://www.mathworks.com/support/compilers/R2013b/index.html, that should be fine, however, when I run mex -setup I still receive the errorError using mex. No supported compiler or SDK was found. Does anyone have any advice or solution on how to point Matlab to the installed compiler? Thanks!
