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