LinearSolverLuKJI_DDRM (ejml-ddense 0.39 API)

java.lang.Object
- org.ejml.dense.row.linsol.LinearSolverAbstract_DDRM
- - org.ejml.dense.row.linsol.lu.LinearSolverLuBase_DDRM
  - - org.ejml.dense.row.linsol.lu.LinearSolverLuKJI_DDRM

All Implemented Interfaces:

org.ejml.interfaces.linsol.LinearSolver<org.ejml.data.DMatrixRMaj,org.ejml.data.DMatrixRMaj>, org.ejml.interfaces.linsol.LinearSolverDense<org.ejml.data.DMatrixRMaj>
```
public class LinearSolverLuKJI_DDRM
extends LinearSolverLuBase_DDRM
```
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_DDRM 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.DMatrixRMaj A)
```
    Specified by:
    
    setA in interface org.ejml.interfaces.linsol.LinearSolver<org.ejml.data.DMatrixRMaj,org.ejml.data.DMatrixRMaj>
    
    Overrides:
    
    setA in class LinearSolverLuBase_DDRM
  - solve
```
public void solve(org.ejml.data.DMatrixRMaj B,
                  org.ejml.data.DMatrixRMaj 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.DMatrixRMaj, org.ejml.data.DMatrixRMaj) 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.
