Package org.ejml.dense.row.linsol.qr

Class 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 AT=QR and the last column in Q is the null space.
