public class LinearSolverLu_FDRM
extends LinearSolverLuBase_FDRM

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.
