WebIn least squares B_h = J_h^T J_h, where J_h = J D. Note that J_h and g_h are proper Jacobian and gradient with respect to "hat" variables. To guarantee global convergence we formulate a trust-region problem based on the Newton step in the new variables: 0.5 * p_h^T B_h p + g_h^T p_h -> min, p_h <= Delta Web2 Oct 2024 · scipy.optimize.least_squares (fun, bounds= (0,1),X) where X = my independent variable data and with the function defined as Y - B1*X1 - B2*X2 - B3*X3 I am unsure …
