Hi I want to include in a Simulink model a block called "Matlab Function" in which I wrote a simple function with the m-file editor. When I try to run my model I have this error:
"Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler."
How can I do? I'm trying to download a compiler as Windows SDK 7.1, but the download is very very slow. Have you got some links to other compilers?
Thank you in advance!

The 64 bit compilers supported for your version are listed at
http://www.mathworks.com/support/compilers/R2011a/win64.html
Anything that is not in that table is not supported.

Try to run "mex -setup" anyway. I thought if you don't have any C compiler, the default lcc will be used. That should be enough if you just want to use MATLAB Function block in a Simulink model for simulation.

Hi Fangjun,
normally: yes. But Fabrizio has a 64Bit MATLAB that comes not with lcc (since lcc is only supported on 32bit).

So. What Can I do? I read about the answer of Derek O'Connor, but He said always to download sdk and visual studio c++ and I can't do it!
Please give me a solution :(

Then install the 32 bit version of MATLAB as well, and start up matlab with the -win32 flag so that you are running the 32 bit version and so would be able to use lcc.
Or get the 64 compiler software shipped to you (or buy it in a store.)

How did you resolve this issue?

VS2010 is not supported for all releases. We would need a more detailed description of the problem (including a copy of what happened with mex -setup) and to know which software releases were involved.

Hi.. m too getting the same error message. I am using windows 8.1, Matlab R2013a 64-bit. I have installed sdk and i have visual studio 2013 installed in my PC. but whenever i run mex -setup, i am getting the same message always.. Please help me to resolve this issue.
mex -setup Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2013a/win64.html
Please choose your compiler for building MEX-files:
Would you like mex to locate installed compilers [y]/n? y
