Webjac bool or callable, optional. If jac is a Boolean and is True, fun is assumed to return the value of Jacobian along with the objective function. If False, the Jacobian will be estimated numerically. jac can also be a callable returning the Jacobian of fun.In this case, it must accept the same arguments as fun.. tol float, optional. Tolerance for termination. WebParameters: func callable. Should take at least one (possibly length N vector) argument and returns M floating point numbers. It must not return NaNs or fitting might fail. M must be greater than or equal to N.. x0 ndarray. The starting estimate for the minimization.
