Class SolveNullSpaceQR_FDRM

java.lang.Object

org.ejml.dense.row.linsol.qr.SolveNullSpaceQR_FDRM

All Implemented Interfaces:

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

public class SolveNullSpaceQR_FDRM
extends java.lang.Object
implements org.ejml.interfaces.SolveNullSpace<org.ejml.data.FMatrixRMaj>

Uses QR decomposition to find the null-space for a matrix of any shape if the number of singular values is known. WARNING: This only uses the first several rows in the input matrix. The rest are ignored.

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