Embedded MATLAB function block in simulink is not working.

Hello,

My MATLAB version is r2010a. I am trying to us Embedded MATLAB function block in simulink and is not working. For example, i am giving a simple input to the block and want to see the output but the model is not going through. It is giving error as below:

Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler.

I installed vs express and run mex -setup and select the Compiler: Microsoft Visual C++ 2008 Express but still is not going through. Can anyone give me solution please? Thank you.

If you have a 64 bit windows and  have'nt yet find a solution to your problem  , I advice you, to install the Matlab 32 bits, that allows you to do what is needed. then after try to resolve your problem as mentioned by Kaustubha. It will be better if you unistall your msv c++ express, then reinstal, NetFramework 4.0 and msv c++ 2008, and Sdk 7.1

You might be missing the Windows SDK installation. Please see this solution for more information. Also, if you are using 64-bit MATLAB, make sure that the "x64 Compilers and Tools" box is selected during the Visual Studio installation (I think only the 32-bit compiler is installed by default) - see this solution for more information.
