WebJan 27, 2024 · Here is a general way using scipy.optimize.curve_fit aiming to fix whatever the polynomial coefficients are desired. import numpy as np from scipy.optimize import … WebIn problems with many points, increasing the degree of the polynomial fit using polyfit does not always result in a better fit. High-order polynomials can be oscillatory between the data points, leading to a poorer fit to the data. In those cases, you might use a low-order polynomial fit (which tends to be smoother between points) or a different technique, …

WebUse polyfit to find a third-degree polynomial that approximately fits the data. p = polyfit (x,y,3) p = 1×4 -0.1917 31.5821 -60.3262 35.3400. After you obtain the polynomial for the fit line using polyfit, you can use polyval to evaluate the polynomial at other points that might not have been included in the original data. Compute the values ... Webx array_like, shape (M,) x-coordinates of the M sample points (x[i], y[i]). y array_like, shape (M,) or (M, K) y-coordinates of the sample points.

WebDec 16, 2010 · POLYFIT3 (X,Y,N,NUL,W) finds the coefficients of a polynomial P (X) of degree N that fits the data, P (X (I))~=Y (I), in a least-squares sense. Any of the coefficients can be forced to be zero, and data can be weighted. NUL is a vector with coefficients forced to be zero in usual order. W is a vector containing the weights of data.
