Detailed Description

Helper class to allow an intuitive syntax for an rank revealing orthogonal factorisation.

This calculates a factorisation CQ=A with orthogonal Q and n x r matrix C where r is typically not much larger than the rank of A. The simplest example is (C(i,k), Q(k,j)) = QC(A(i,j)) to calculate the CQ decomposition of A. However A, Q and C can also be a higher order Tensors.
