Python: Fit error function (erf) or similar to data
Oct 17, 2015 · You can fit any function you want: from scipy.optimize import curve_fit popt, pcov = curve_fit(func, xdata, ydata) In case you want some function similar to erf, you can use for example: def func(z,a,b): return a*scipy.special.erf(z)+b This will find the parameters a,b.

Python 求高斯误差函数 erf、erfc、erfi - CSDN博客
May 13, 2024 · 本文将对误差 函数 （ERror Function, ERF）进行简单的介绍，并探索如何用 Python 来求 误差函数。 更多与之相关的理论知识可以参看 关于高斯函数 / 高斯分布 / 高斯误差函数的探讨. 有的地方叫做『误差补函数』或『互补误差函数』，这里我随意取成了误差函数补（ERror Function Complement, ERFC）。 一是参考了『舒尔补』这一名字，二是和字母顺序保持一致。 误差函数补（ERror Function Complement, ERFC）的定义式如下.
