1. Introduction Finite Element Analysis (FEA) is a numerical technique for solving engineering problems such as structural analysis, heat transfer, fluid flow, and electromagnetics. MATLAB, with its powerful matrix manipulation capabilities and high-level programming environment, is an excellent platform for implementing FEA from scratch using M-files. % Assembly dof_list = [(n1-1)*2+1, (n1-1)*2+2,
% Area area = 0.5 * abs((x(2)-x(1))*(y(3)-y(1)) - (x(3)-x(1))*(y(2)-y(1))); % Assembly dof_list = [(n1-1)*2+1
