ABSTRACT

In this article, an attempt has been made to explain and code the Thomas algorithm, also called TDMA (Tridiagonal matrix algorithm) in Python. A step-by-step algorithm has been developed, and the methodology has been presented for programming. The developed TDMA function has been tested with the help of two numerical problems, and accurate results have been obtained. This article will help the students with numerical computations while developing their codes for different numerical problems.

Keywords: TDMA, Thomas algorithm, Tridiagonal Matrix, Python programming, Numerical heat transfer
