public boolean setA(org.ejml.data.DenseMatrix64F A)

quality

public double quality()

invert

public void invert(org.ejml.data.DenseMatrix64F A_inv)

Specified by:

invert in interface org.ejml.interfaces.linsol.LinearSolver<org.ejml.data.DenseMatrix64F>

improveSol

public void improveSol(org.ejml.data.DenseMatrix64F b,
                       org.ejml.data.DenseMatrix64F x)

This attempts to improve upon the solution generated by account for numerical imprecisions. See numerical recipes for more information. It is assumed that solve has already been run on 'b' and 'x' at least once.

Parameters:

b - A matrix. Not modified.

x - A matrix. Modified.

modifiesA

public boolean modifiesA()

modifiesB

public boolean modifiesB()

getDecomposition

public LUDecompositionBase_D64 getDecomposition()
