Why a real-valued scalar multiply a Hermitian matrix isn't be a Hermitian matrix?

[7tosmoke]

Hello，I‘m new in cvxpy and I found a question when I coded.

Why a real-valued scalar multiply a Hermitian matrix isn't be a Hermitian matrix?
Like Y=1*X, while X = cp.Variable((3,3), hermitian=True).
Then, Y.is_hermitian() outputs False.
Could you help me?
Thanks a lot.

This is a great question. The answer is that symbolic properties like is_hermitian aren’t as reliably inferred as properties like is_dcp. We can easily update the code so that we check for real scalar multiplication though. Thanks for catching this!

Thank you for your reply! I have already fixed my problem with adding other cvx functions. Hope your package become better!
