What is FEM Poisson Code Explained about?

This document provides a detailed line-by-line explanation of a MATLAB finite element method (FEM) code for solving the 2D Poisson equation, structured according to NPTEL lecture material. It covers various aspects including the governing equation, element types, boundary conditions, and the main driver script, which sets up problem parameters, assembles matrices, and processes results. The code utilizes bilinear quadrilateral elements and Gauss quadrature integration to compute solutions under specified th
