I am trying to fit this function to some data: But when I use my code import numpy as np from scipy.optimize import curve_fit import matplotlib.pyplot as plt def f(x, start, end): res = np.empty...

I am trying to deconvolve complex gas chromatogram signals into individual gaussian signals. Here is an example, where the dotted line represents the signal I am trying to deconvolve. I was able ...

I would like to fit ellipsometric data to complex model using LMFit. Two measured parameters, psi and delta, are variables in a complex function rho. I could try with separating problem to real an...

I was adopting lmfit to do a curve fitting and use that fitted model to do prediction. However, the following code did not achieve what I want. Could you please help? Thanks. import numpy as np fr...

This post is related to my other one where I was told to use lmfit to fix my problem. I installed lmfit in anaconda Prompt with conda install --channel "conda-forge" lmfit which worked. But now w...

I'm trying to build a model using lmfit (link to docs) and I can't seems to find out why I keep getting a ValueError: The input contains nan values when I try to fit the model. from lmfit import m...

I have experimental data : xdata = [85,86,87,88,89,90,91,91.75,93,96,100,101,102,103,104,105,106,107.25,108.25,109,109.75,111,112,112.75,114,115.25,116,116.75,118,119.25,120,121,122,122.5,123.5,12...

Is there a way to construct a an lmfit Model based on a function with an arbitrary number of dependent variables? For example: from lmfit import Model def my_poly(x, *params): func = 0 for i in...

I have installed lmfit trough PIP pip install lmfit==0.7.2 importing lmfit in ipython notebook seems to work. That is, the import does not give any error messages and I can call a bunch of fun...

I would like to use the lmfit module to fit a function to a variable number of data-sets, with some shared and some individual parameters. Here is an example generating Gaussian data, and fitting ...
