slsf error using Matlab Function block in Simulink

I am trying to use the Matlab Function block in Simulink. I'm running Matlab R2013a 32-bit on a 64-bit Windows laptop.

I get the following Simulink error: Error using slsf (line 119) CRL: "Simulation Target IPP BLAS" cannot be found in the registry.

I don't think the error has anything to do with the contents of the Matlab Function block I am running. I get the same error even with a nearly empty Matlab Function block.

I have tried uninstalling Matlab, cleansing the registry of any Matlab references, and reinstalling Matlab. I have also tried running these same Matlab Function blocks on a friend's laptop also running Matlab R2013a and the blocks run fine, even though we couldn't find any reference to a "Simulation Target IPP BLAS" in his registry.

So I am at a loss. Any ideas how to fix this problem?

Could you try the suggestion in this previously answered question and see if it works for you?

[Damon]

Kaustubha I saw that suggestion but it did not apply to me. Thank you anyway for your idea.

[Kaustubha Govind]

Could you also run the following commands in MATLAB and try running the model again:

>> rehash toolbox
>> rehash toolboxcache

[Damon]

I still get the same error.

[Kaustubha Govind]

Please try contacting MathWorks Tech Support.

[Damon]

I'll do that. Thanks.

Did you receive any answer for this issue? I just upgraded from 2012a to 2013a on Ubuntu 12.04 and I get this error to. Thx

I get this error only when I am trying to used a user defined MATLAB function in my model? Any idea what may be causing this? Did you get any fix from Mathworks?

[Damon]

Sorry to say I never really found out what caused the issue. Tech support couldn’t replicate my problem so it must be an environment-related issue. I did the following things and then the Matlab function block started working again.

• Uninstalled all Matlab versions, deleted all preference files and Matlab file folders and ran a registry repair program. • Installed only Matlab R2013a • Rehash path • Rehash toolbox • Rehash pathreset • Rehash toolboxreset • Rehash toolboxcache

I coded the last 5 commands in a startup m-file that I run at every Matlab startup.

I have no idea if this will work for anyone else.
