I'm having a bit of trouble with fitting a curve to some data, but can't work out where I am going wrong. In the past I have done this with numpy.linalg.lstsq for exponential functions and scipy.op...

How can I do a maximum likelihood regression using scipy.optimize.minimize? I specifically want to use the minimize function here, because I have a complex model and need to add some constraints. I...

Following this question which asks (and answers) how to read .mat files that were created in Matlab using Scipy, I want to know how to access the fields in the imported structs. I have a file in M...

Solve_ivp is an initial value problem solver function from Scipy. In a few words scipy.integrate.solve_ivp(fun, t_span, y0, method=’RK45’, t_eval=None, dense_output=False, events=None, vectorized=...

I am willing to apply Fourier transform on a time series data to convert data into frequency domain. I am not sure if the method I've used to apply Fourier Transform is correct or not? Following is...

In this question I asked the community about how scipy.interpolate.splev calculates a spline basis.. My goal was to compute a spline faster then splev by pre-calculating a bspline basis and generat...

I am writing Python script to code for finding probability of Hypergeometric distribution. When I am using hypergeom() function in scipy, it is showing like below: scipy.stats.distributions.rv_fro...

A recent immigrant to Python and scientific computing with Python. This is a question to avoid any duplication of code that might already exist. I have a field that is sampled as a function of x a...

Function argrelextrema from scipy.signal does not detect flat extrema. Example: import numpy as np from scipy.signal import argrelextrema data = np.array([ 0, 1, 2, 1, 0, 1, 3, 3, 1, 0 ]) argrelex...

I want to fit non-negative parameters (xs in the code) to a function fp, given by where v and L are fixed, given parameters. Computing fp can be done relatively quickly by vectorizing it and using...

I'm trying to solve a second order ODE using odeint from scipy. The issue I'm having is the function is implicitly coupled to the second order term, as seen in the simplified snippet (please ignore...

I am currently working with some Raman Spectra data, and I am trying to correct my data caused by florescence skewing. Take a look at the graph below: I am pretty close to achieving what I want....

I have two ndarray A and B, one has the shape (4,) and another (4,1). When I want to calculate the cosine distance using this, it throws some exceptions that complains the two objects are not alig...

I'm having a hard time getting into numpy. What I want in the end is a simple quiver plot of vectors that have been transformed by a matrix. I've read many times to just use arrays for matrices, fa...

Does python have a built-in function that converts a matrix into row echelon form (also known as upper triangular)?

I have some more or less linear data of the form: x = [0.1, 0.2, 0.4, 0.6, 0.8, 1.0, 2.0, 4.0, 6.0, 8.0, 10.0, 20.0, 40.0, 60.0, 80.0] y = [0.50505332505407008, 1.1207373784533172, 2.19818447190200...
