You can use these solvers:
- fsolve is a robust function for solving systems of nonlinear equations. It requires an initial guess for the variables and attempts to find a solution that zeroes the system. Refer to this link: https://www.mathworks.com/help/optim/ug/fsolve.html
- lsqnonlin: Useful if you can reformulate your problem as a least-squares problem. Refer to this link: https://www.mathworks.com/help/optim/ug/lsqnonlin.html
I hope it will help.
