Expanded QR Decomposition Object

DESCRIPTION:

These are objects of class expand.qr.Matrix They represent the QR decomposition of a matrix.

GENERATION:

This class of objects is returned from the expand.qr.Matrix function to represent a QR decomposition. The following components must be included in a legitimate "expand.qr.Matrix" object:

VALUE:

q
The orthogonal factor.
r
The factor containing an upper triangular factor portion.
permutation
The column permutation applied to the original matrix in order to obtain the factorization.
