用python拟合曲线 [英] curve fitting with python

问题描述

我正在尝试容纳一些数据和东西，我知道有一个简单的命令可以使用python/numpy/matplotlib来做到这一点，但是我找不到它.我认为是

I'm trying to fit some data and stuff, I know there is a simple command to do this with python/numpy/matplotlib, but I can't find it. I think it is something like

popt,popc = numpy.curvefit(f,x)

其中，popt是f的参数，popc是拟合质量，f是f的预定义函数.你们中有人知道吗?

where popt is the paramters of f, popc is the fit quality and f is a predefined function of f. Does any of you know it?

推荐答案

看看

scipy.optimize.curve_fit(f，xdata，ydata，p0 = None，sigma = None，** kw)

scipy.optimize.curve_fit(f, xdata, ydata, p0=None, sigma=None, **kw)

使用非线性最小二乘法将函数f拟合到数据中.

Use non-linear least squares to fit a function, f, to data.
