How to find "Index exceeds matrix dimensions" error in Simulink

I am running a Simulink model (MATLAB v. 15), and it gives me an error message (without running), stating "Index exceeds matrix dimensions". It gives me no other information (which model it is occurring in, which variable has an index which is being exceeded, etc.)

Is there a file that states where this is occurring? Is there some other means to determine where this is happening? The model is fairly large, and includes StateFlow control blocks, Matlab blocks, etc.

By MATLAB v. 15, I assume you meant R2006a. Can you try the model in a recent release, e.g., R2017a? In the newer version, there might be a more informative error message.

I'm sorry, I meant with MATLAB 2015b

Please try using the following command line interface and see if more information is available from the command line output.

set_param(gcs,'SimulationCommand','update');

Otherwise, try "binary-search" on the model to find problematic block.
