class Fac_LQ extends Factorization with Error

The Fac_LQ class provides methods to factor an 'm-by-n' matrix 'aa' into the product of two matrices, when m < n.

'l' - an 'm-by-m' left lower triangular matrix 'q' - an 'm-by-n' orthogonal matrix and

such that 'aa = l * q'. Note, orthogonal means that 'q.t * q = I'.
