Class QrHouseHolderSolver_DDRB

All Implemented Interfaces:
LinearSolver<DMatrixRBlock,DMatrixRBlock>, LinearSolverDense<DMatrixRBlock>

public class QrHouseHolderSolver_DDRB extends Object implements LinearSolverDense<DMatrixRBlock>

A solver for QRDecompositionHouseholder_DDRB. Systems are solved for using the standard QR decomposition method, sketched below.

A = Q*R
A*x = b
Q*R*x = b
R*x = y = QTb
x = R-1y

Where A is the m by n matrix being decomposed. Q is an orthogonal matrix. R is upper triangular matrix.
