la_lapack::unmlq Interface Reference

UNMLQ: overwrites the general complex M-by-N matrix C with SIDE = 'L' SIDE = 'R' TRANS = 'N': Q * C C * Q TRANS = 'C': Q**H * C C * Q**H where Q is a complex unitary matrix defined as the product of k elementary reflectors Q = H(k)**H . . . H(2)**H H(1)**H as returned by CGELQF. Q is of order M if SIDE = 'L' and of order N if SIDE = 'R'. More...
