All Implemented Interfaces:

org.ejml.interfaces.linsol.LinearSolver<org.ejml.data.FMatrixRMaj,org.ejml.data.FMatrixRMaj>, org.ejml.interfaces.linsol.LinearSolverDense<org.ejml.data.FMatrixRMaj>
```
public class LinearSolverLuKJI_FDRM
extends LinearSolverLuBase_FDRM
```
To avoid cpu cache issues the order in which the arrays are traversed have been changed. There seems to be no performance benit relative to LinearSolverLu_FDRM in this approach and b and x can't be the same instance, which means it has slightly less functionality.

```
- Method Detail
  - setA
```
public boolean setA(org.ejml.data.FMatrixRMaj A)
```
    Specified by:
    
    setA in interface org.ejml.interfaces.linsol.LinearSolver<org.ejml.data.FMatrixRMaj,org.ejml.data.FMatrixRMaj>
    
    Overrides:
    
    setA in class LinearSolverLuBase_FDRM
  - solve
```
public void solve(org.ejml.data.FMatrixRMaj B,
                  org.ejml.data.FMatrixRMaj X)
```
    An other implementation of solve() that processes the matrices in a different order. It seems to have the same runtime performance as solve(org.ejml.data.FMatrixRMaj, org.ejml.data.FMatrixRMaj) and is more complicated. It is being kept around to avoid future replication of work.
    
    Parameters:
    
    B - A matrix that is n by m. Not modified.
    
    X - An n by m matrix where the solution is writen to. Modified.
