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.

We solve it by using the following instructions. Matlab. y(1)=b(1);.

L U decomposition - MATLAB Answers - MATLAB Central, lower–upper (LU) decomposition or factorization factors a matrix as the product of a lower triangular

If A is an upper or lower triangular matrix, employ a backward substitution algorithm. The inaccuracy of d is due to an aggregation of round-off errors in the MATLAB® implementation of the LU decomposition, which det uses to calculate the determinant. This result demonstrates a few important aspects of calculating numeric determinants.
