% Define the element stiffness matrix hx = 1/nx; % element size in x-direction hy = 1/ny; % element size in y-direction Ke = (1/4)*[2 -2 -1 1; -2 2 1 -1; -1 1 2 -2; 1 -1 -2 2]/ (hx*hy);

% Compute the load vector F = zeros(nx+1, 1); for i = 1:nx+1 F(i) = f(i*k); end matlab codes for finite element analysis m files

% Assemble the global stiffness matrix K = zeros(nx+1, nx+1); for i = 1:nx K(i:i+1, i:i+1) = K(i:i+1, i:i+1) + Ke; end % Define the element stiffness matrix hx =
