Implementing Integration Limits when using Numerical Integration Question: I’m using numerical integration to model the trajectory of a particle passing through a non-uniform magnetic field. I’m specifically using a Markov Chain Monte Carlo algorithm (Metropolis-Hastings) that allows me to calculate model data in order to fit the actual particle’s data. The issue that I have …

evaluation of polynomials of order 15 gives unexpected results (OpenCV Coordinates Output Python) Question: I’ve created a formula with polynomial regression to calculate a drag point from an input. I tested the formula in a separate file with the input, and the output appears to be working as intended. However, in the actual file, it …
How to do cubic spline interpolation and integration in Pytorch Question: In Pytorch, is there cubic spline interpolation similar to Scipy’s? Given 1D input tensors x and y, I want to interpolate through those points and evaluate them at xs to obtain ys. Also, I want an integrator function that finds Ys, the integral of …
How to improve my performance in filling gaps in time series and data lists with Python Question: I’m having a time series data sets comprising of 10 Hz data over several years. For one year my data has around 3.1*10^8 rows of data (each row has a time stamp and 8 float values). My data …
Is it possible to set a number to NaN or infinity? Question: Is it possible to set an element of an array to NaN in Python? Additionally, is it possible to set a variable to +/- infinity? If so, is there any function to check whether a number is infinity or not? Asked By: Bob …
