Is there any standard function in Mathematica to do this? Its very unusual that a normal *-product of matrices occurs in multilinear equations and the more if an analytical solution is sought for. The element by element product M*m1=m1*M has no coordinate invariant meaning and no invariant relation to M since it is a map by projections on coordinate pairs with a different scaling factor in each pair. So it will make sense only if m1 is a special tensor product of vectors respecting a coherent symmetric product structure of the scaling factors m1_ik =s_i * s_k as far as I can see. -- Roland Franzius
