• Nov 9, 2025 lu decomposition using doolittle algorithm matlab titution to solve \( Ly = b \) Backward substitution to solve \( Ux = y \) Example: ```matlab b = [1; 4; 3]; % Forward substitution y = zeros(size(b)); for i = 1:length(b) sumY = 0; for k = 1:i-1 sumY = sumY + L(i,k)y(k); end y(i) = b(i) - sumY; end By Norma Ebert
