Solving Banded Linear Systems in Python (Part 4)

We’ve talked at length about sparse matrices in the previous videos. It turns out that a lot of practical problems produce systems that have a fairly specific shape- a banded matrix. I had assumed Scipy’s sparse solver would reconginze the matrix is banded and use an appropriate algorithm. Evidently, this is not the case. There is, however, a banded solver that can be called specifically. In this video, I briefly go over how to use it and show the performance enhancement over the generic spsolve command.
