In the course of solving a least-squares problem I have worked the thing down to a stumbling block: how does one solve min ||AX - XB|| subject to the constraint that X be unitary? A is a complex matrix; B is upper triangular and Toeplitz, if that helps at all. It doesn't matter to me if the matrix norm is Frobenius or 2-norm. Solutions and/or references to the literature would be most welcome. Thanks, -- ------------------------------------------------------------------ Dr. Stephan V.
