sorg2l L generates an m by n real matrix Q with orthonormal columns, which is defined as the last n columns of a product of k elementary reflectors of order m
Q = H(k) . . . H(2) H(1)
as returned by SGEQLF.
TAU(i)
must contain the scalar factor of the elementary
reflector H(i), as returned by SGEQLF.
