Dear Sir, I want to solve a nonlinear matrix system. The equation is as " b-(a*x)*(a'*x*a)^-1=0 " where "a" and "b" are as the matrix form. Can you help me to solve this matrix equation in MATLAB? Thanks and best, Mohsen Akbari M.Sc. in Power Systems Engineering Electrical Engineering Department K.N. Toosi University of Technology Tehran, Iran E-Mail: [email protected], [email protected]
