IDENMAT() gives the "Error: Invalid input" error message when the value is 33 or above, for example IDENMAT(33) will give this error, but IDENMAT(32) won't. This is probably a bug and not caused memory constraint because I can generate a 100x100 matrix just fine.

This happens on HP Prime Virtual Calculator and Version A, Build 2.1.14425 (2020 1 16).

I was trying to test a whether a given matrix is an identity matrix M1==IDENMAT(rowDim(M1)). I would appreciate if someone can tell me another way that is as easy.
