[L,U,P] = lu(X) returns an upper triangular matrix in U, a lower triangular matrix L with a unit diagonal, and a permutation matrix P, so that LU = PX. Y = lu(X) returns a matrix Y, which contains the strictly lower triangular L, i.e., without its unit diagonal, and the upper triangular U as submatrices.

, so that the above equation is fullfilled. You should then test it on the following two examples and include your output.

If you had for example a diagonal coefficient that was equal to 0 when you tried to do the conventional LU decomposition algorithm, it will not work as the diagonal coefficients are required when performing the Gaussian elimination to create the upper triangular matrix U so you would get a divide by zero error.

If you use 'matrix' instead of 'vector', then lu returns permutation matrices, as it does by default. L and U are nonsingular if and only if A is nonsingular.

Compute the LU factorization of a matrix and examine the resulting factors. LU factorization is a way of decomposing a matrix A into an upper triangular matrix U, a lower triangular matrix L, and a permutation matrix P such that PA = LU.
