This is an example from the Scipy-User mailing list. max(y_data), 0.1, 140, -0.1, 270]) p2, C, info, msg, success = optimize.leastsq(errfunc, guess, args=(t, 21 Oct 2004 The easiest way to understand this is with an example of its usage: >>> mgrid[0:5,0:5] array([[[0 from scipy.optimize import leastsq >>> plsq Introduction; Using an algebraic approximation; Using scipy.optimize.leastsq. Basic usage .. Here is an example with data points all around the circle:. For example, suppose it is desired to fit a set of data ( \left{ \mathbf{x}{i}, 1.0472] >>> from scipy.optimize import leastsq >>> plsq = leastsq(residuals, p0, Initial guess for the parameters 5 p1, success = optimize.leastsq(errfunc, p0[:], . p = r[T, p1, p2] 11 # Cost function of the fit, compare it to the previous example. The data used in this tutorial are lidar data and are described in details in the . scipy.optimize.leastsq minimizes the sum of squares of the function given as an scipy.optimize.leastsq(func, x0, args=(), Dfun=None, full_output=0, col_deriv=0, ftol=1.49012e-08, xtol=1.49012e-08, gtol=0.0, maxfev=0, epsfcn=None, This page provides python code examples for scipy.optimize.leastsq. The examples are extracted from open source python projects from GitHub. Note that the Rosenbrock function and its derivatives are included in scipy.optimize . The implementations shown in the following sections provide examples of There also examples at wiki.scipy.org/Cookbook/FittingData and from scipy.optimize import leastsq import numpy as np import
