Return Value
A Complex matrix containing L, the lower triangular portion of the LU factorization of a.Remarks
Scaled partial pivoting is used to achieve the LU
factorization. The resulting factorization is such that
, where A is the input matrix
a, P is the permutation matrix
returned by GetPermutationMatrix,
L is the lower triangular matrix returned by
GetL, and U is the unit upper triangular matrix
returned by GetU.

L is the lower triangular matrix returned by
GetL, and U is the unit upper triangular matrix
returned by GetU.
