Small hessian squares
WebbWhen method is ‘leastsq’ or ‘ least_squares ’, the objective function should return an array of residuals (difference between model and data) to be minimized in a least-squares sense. With the scalar methods the objective function can either return the residuals array or a single scalar value. The function must have the signature: Webb5 juni 2024 · Using Hessian for least squares problem.
