WebDec 30, 2024 · Fixed point continuation (Ma, Goldfarb, & Chen, 2011) is an optimization algorithm for solving matrix completion problems. It transforms problem (2) into an unconstrained optimization problem for an iterative solution. WebDescription FindRoot fails to give a correct solution to a system of nonlinear algebraic equations unless a good initial guess is chosen. Difficulty in finding a suitable initial guess is avoided by using homotopy continuation methods such as the fixed point and the Newton homotopy methods. Subjects Applied Mathematics
