java.lang.Object

org.ejml.dense.row.linsol.qr.SolveNullSpaceQRP_DDRM

All Implemented Interfaces:

org.ejml.interfaces.SolveNullSpace<org.ejml.data.DMatrixRMaj>

public class SolveNullSpaceQRP_DDRM
extends java.lang.Object
implements org.ejml.interfaces.SolveNullSpace<org.ejml.data.DMatrixRMaj>

Uses QR decomposition to find the null-space for a matrix of any shape if the number of singular values is known.=

Solves for A^T=QR and the last column in Q is the null space.
