Hi Nandish,
I understand that when you use the 'hasChanged' function in your Stateflow chart, you encounter an error that indicates that your input PS is a matrix or structure and therefore cannot be used with change detection.
If you are using MATLAB as your action language, you unfortunately can only use a scalar value as input to hasChanged. If you would like to use vector or matrix inputs with hasChanged, please use C as your action language instead. See the note in the "hasChangedTo" section of the change detection documentation for more information:
