% Assemble the global stiffness matrix K = zeros((nx+1)*(ny+1), (nx+1)*(ny+1)); for i = 1:nx for j = 1:ny idx = (i-1)*(ny+1) + j; K(idx:idx+1, idx:idx+1) = K(idx:idx+1, idx:idx+1) + Ke; end end idx:idx+1) = K(idx:idx+1

To keep your MATLAB scripts efficient, follow these industry standards: idx:idx+1) + Ke
