Module scid.ports.minpack.hybrd


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.
