hybrd(fcn, n, x, fvec, xtol, maxfev, ml, mu, epsfcn, diag, mode, factor, nprint, info, nfev, fjac, ldfjac, r, lr, qtf, wa1, wa2, wa3, wa4)The purpose of hybrd is to find a zero of a system of n nonlinear functions in n variables by a modification of the Powell Hybrid Method. The user must provide a function which calculates the functions. The Jacobian is then calculated by a forward-difference approximation.
