Unformatted text preview: [L,U,P]=lu(A) It takes as input A and returns L , U and the permutation matrix P such that L * U = P * A . One you have these matrices, to solve a system A x = b , you can use the following commands b=P*b y=L\b x=U\y Use the LU factorization to analyze the truss in A3.4 with the follow-ing choices of W 3 : W 3 = 10, 50, 150, 200, 250. Recall you only need to compute the LU factorization once. Hand in all matlab m-ﬁles, diaries, and scripts....
