I get a 'LU decomposition' error where using SARIMAX in the statsmodels python package. This is the code:

3 days ago · Matrices can be triangulated using less than ten lines of code in C, I have heard being said. But LU decomposition method needs to be used, instead of Cramer's rule. So, I was trying to do that. …

I want to implement my own LU decomposition P,L,U = my_lu (A), so that given a matrix A, computes the LU decomposition with partial pivoting. But I only know how to do it without pivoting.

LU decomposition without pivoting is rarely seen in practice. It's primarily used to introduced people to the idea of the technique, then the introduction builds by introducing pivoting.
