I am using the Responce optmization toolbox to optmize my controller and I am getting the following error:
=== Design Optimization (Elapsed: 0.253 sec) ===
Error:Brace indexing is not supported for variables of this type.
What I dont understand is the model will run for a while and succesful test different parameters. I can monitor the output and the convergres of the system. Then it will just throw the above error at some point. What is cauing this error. It would really help if it told me where this is occuring so I can track the error.

Right but how can I nail down exactly where the error is happening? The stack trace is terrible.

Run "dbstop if error" in MATLAB Command Window first and then run your optimization. Hopefully you will be able to see the line of the source code when the error happens.

If the error pops up at the Simulink diagnostic window, you may not be able to see where in the source the error happened. But try it anyway.
