I cannot run dsm_demo.mdl

Dear all,

I had a problem when I followed this tutorial:

http://www.mathworks.com/help/simulink/ug/using-global-data-with-the-matlab-function-block.html How to Use Data Store Memory Blocks

I typed the following code in order to open dsm_demo.mdl:

open_system([docroot, '/toolbox/simulink/examples/dsm_demo'])

But when I tried to run the simulation, I got the following error message:

Please, Do you have any idea, how I can run this tutorial?

Thanks in advance!

Since the MATLAB Function block (in releases earlier than R2015a) always generates C code, you need to install and configure a supported C compiler to do so.

What version of MATLAB are you using and on which operating system? For example, the list of Windows 32-bit supported compilers for R2012b is here:

http://www.mathworks.com/support/compilers/R2012b/win32.html

You'll see there's a table for the Simulink product family, and the second column says "For model referencing, Accelerator mode, and MATLAB Function blocks".

After you have one of those installed, you can type mex -setup in MATLAB and it should guide you through setting that up.

Thank you for your answer!

I have already found this link but I had problem with installing Windows SDK 7.1 for NETFramework 4 onWindows 7 (I have MatLab 2013a).

But for others who have the same problem: This link helped me:

Now everything works :)
