how to implement levenberg marquardt algorithm to find the kruppa coefficient matrix?

sir, i need to find intrinsic parameters using kruppa equations. To obtain intrinsic parameter matrix kruppa coefficient matrix should be computed. To do so we have to minimize the equation using levenberg marquardt algorithm. Please help me to obtain intrinsic parameters.

Answer 1

In the Optimization Toolbox, the solvers FSOLVE and LSQNONLIN both have a Levenberg-Marquardt option.
