-*
-* H = I - tau * v * v**H
-*
-* where tau is a complex scalar and v is a complex vector.
-*
-* If tau = 0, then H is taken to be the unit matrix.
-*
-* To apply H**H (the conjugate transpose of H), supply conjg(tau) instead
-* tau.
-*
-* H is a product of k elementary reflectors as returned by ZTZRZF.
