LU Factorization (Not in Base Package)

Performs the LU factorization of a real, square matrix A. Details

A must be a square, real matrix.
L is a lower triangular matrix.
U is an upper triangular matrix.
P is a permutation matrix.
error returns any error or warning condition from the VI.

LU Factorization Details

LU factorization factors the square matrix A into two triangular matrices; one is a lower triangular matrix L with ones on the diagonal, and the other is an upper triangular matrix U, so that PA=LU, where P is a permutation matrix, which serves as the identity matrix with some rows exchanged.

Factorization serves as a key step for inverting a matrix, computing the determinant of a matrix, and solving a linear equation.
