TDecompQRH Class Reference

QR Decomposition class.

Decompose a general (m x n) matrix A into A = fQ' fR H where

fQ : (m x n) - internal Q' matrix (not orthoginal)
fR : (n x n) - upper triangular matrix
H : HouseHolder matrix which is stored through
fUp: (n) - vector with Householder up's
fW : (n) - vector with Householder beta's

Double_t x[n]
Definition legend1.C:17
const Int_t n
Definition legend1.C:16
TMarker m
Definition textangle.C:8

If row/column index of A starts at (rowLwb,colLwb) then the decomposed matrices start from :

fQ' : (rowLwb,0)
fR : (0,colLwb)
and the decomposed vectors start from :
fUp : (0)
fW : (0)

In order to get the QR dcomposition of A (i.e. A = QR ) The orthoginal matrix Q needs to be computed from the internal Q' and the up's and beta's vector defining the Householder transformation

The orthogonal Q matrix is returned to the user by calling the function TDecompQRH::GetOrthogonalMatrix()

Errors arise from formation of reflectors i.e. singularity . Note it attempts to handle the cases where the nRow <= nCol .
