Undefined variable "emlcoderprivate" error when running Stateflow on Matlab 2012b

Hi,

I am very new to Stateflow, and I have created a simple state machine on Matlab 2012b (32-bit version). Whenever I try to an Update Diagram or start the simulation, I get the following model error message:

"Undefined variable "emlcoderprivate" or class "emlcoderprivate.compiler_supports_eml_ipp".

I have tried using Microsoft Visual C++ 2010 Express as the compiler, but I still get the same error message.

Can anyone please help me shed some light into this?

Thank you so much for all of your help, Victoria

Hi Victoria,

I faced a similar problem using my Matlab... I use Matlab 2010b. My mentor helped me solve this error. Usually such an error is caused when there is some issue with the matlab path. Type "restoredefaultpath" in the Matlab command window and that should solve the problem. It did in my case. Now when you re-open Matlab, you might get an error if the default directory is set to Windows. You can change that by right-clicking on the Matlab icon -> select "Properties" -> specify any path other than Windows in the field "Start in". Restart matlab using the same icon and the error will not appear. Hope this helps!

what do you mean by saying"Now when you re-open Matlab, you might get an error if the default directory is set to Windows. You can change that by right-clicking on the Matlab icon -> select "Properties" -> specify any path other than Windows in the field "Start in". ”

In Windows Explorer you can right-click on the icon for MATLAB and select Properties and change the Start In directory to your home directory.
