MATLAB is a powerful environment for Finite Element Analysis (FEA) because its core architecture is designed for matrix operations, which are the foundation of the Finite Element Method (FEM)
% Define the problem parameters
Lx = 1; Ly = 1; % Length of the domain
Nx = 10; Ny = 10; % Number of elements
g = @(x, y) sin(pi*x).*sin(pi*y); % Source term
% Coordinates of nodes
x1 = nodes(n1,1); y1 = nodes(n1,2);
x2 = nodes(n2,1); y2 = nodes(n2,2);
