public interface ILUPResult
extends ILUResult

Interface for results of LUP decomposition

LUP Decomposition refactors the original matrix such that:

P^T*L*U = A

where P is a pivot matrix, L is a lower triangular matrix, U is an upper triangular matrix and A is the original matrix.

LUP Decomposition is useful since once the decomposition has been performed linear equations can be quickly solved and the original matrix A inverted. Different algorithms can be selected to perform the decomposition, all will have the same end result.
