Nice question

Muhammad Ali

I think the only one is if the matrices are identity or symmetric positive definite. For Hilbert Operator theory you may follow http://web.math.ku.dk/~durhuus/MatFys/MatFys4.pdf

Dr Kamran Zakaria

Thanks, Mr. Joseph Shomberg

for your contribution.

Thanks, Mr. Muhammad Ali for your answer.
