Remarks
LU factorization is a procedure for decomposing an matrix into a product
of a lower triangular matrix and an upper triangular matrix. Given a
matrix A, instances of the DoubleLUFact class factor A as follows:
CopyC#
where P is a permutation matrix, L is a lower triangular matrix
with ones on the diagonal, and U is an upper triangular matrix.
A DoubleLUFact instance is constructed by supplying a matrix to factor. An existing instance can be used to factor other matrices with the provided Factor() method. Read-only properties provide access to the permutation matrix P, lower triangular matrix L, and upper triangular matrix U.
