Currently getting a domain error when running Simulink code. No indication where the error is occurring.

I'm getting the following error when running my simulink code:

Domain error. To compute complex results from real x, use 'asin(complex(x))'.

The model builds fine, but a few seconds into running this error comes up. The error dialog does not tell me where this error is occuring. I have several matlab function blocks that call asin, but can't tell which one is causing the problem.

Is this a bug? Is there a way to narrow down what block the error is occurring in?

Hi Dave.

I face the same problem. I cannot locate where the error is occuring either.

Did you find a solution?

I had this same problem, including the error dialog not telling me the location of the problem. The root problem is an input to asin that is outside the range -1 to 1. My issue turned out to be in a linked library block, which is a User-Defined MATLAB Function, so apparently the Simulink error reporting algorithm does not trace into such.
