Reproducing the error: pipenv install scikit-learn WebA and B are both diagonal matrices. There exists an invertible matrix P such that P − 1 A P and P − 1 B P are both diagonal. 1. A = c B or A = c B − 1 or B = 0. This is too long for a comment, so I posted it as an answer. I think it really depends on what A or B is. For example, if A = c I where I is the identity matrix, then A B = B A ... cissy houston\\u0027s father nitcholas drinkard
