public class QRDecomposition
extends Object
implements Computation<Pair<Matrix<DRes<SFixed>>,Matrix<DRes<SFixed>>>,ProtocolBuilderNumeric>

Compute the QR-decomposition of an mxn-matrix A with m ≥ n and full column rank. The QR-decomposition is a pair of matrices (Q,R) with A = QR and where Q is an mxn-matrix with orthonormal columns and R is an upper-triangular nxn-matrix.
