Class SolveNullSpaceQR_FDRM

All Implemented Interfaces:

@Generated("org.ejml.dense.row.linsol.qr.SolveNullSpaceQR_DDRM") public class SolveNullSpaceQR_FDRM extends Object implements SolveNullSpace<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.
