Hi everyone, Given C = A*B, where A, B, and C are n x n matrices, and * represents a matrix product, I am looking for pointers on how the eigen values of C are related to those of A and B. If necessary, I also know that A and B are real, non-negative, and stochastic. We do know that, for C = A*A = A^2 eig(C) = eig(A)^2 (elementwise) Thank you, Kumar
