All Implemented Interfaces:

LinearSolver<CDenseMatrix64F>

public class LinearSolverLu_CD64
extends LinearSolverLuBase_CD64

For each column in the B matrix it makes a copy, which is then solved for and writen into X. By making a copy of the column cpu cache issues are reduced.

Description copied from interface: LinearSolver

Solves for X in the linear system, A*X=B.

In some implementations 'B' and 'X' can be the same instance of a variable. Call LinearSolver.modifiesB() to determine if 'B' is modified.

Parameters:

b - A matrix ℜ ^{m × p}. Might be modified.

x - A matrix ℜ ^{n × p}, where the solution is written to. Modified.
