+*
+*  -- LAPACK routine (version 3.1) --
+*     Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..
+*     November 2006
+*
+*     .. Scalar Arguments ..
+      CHARACTER          SIDE, TRANS
+      INTEGER            INFO, K, LDA, LDC, M, N
+*     ..

+      COMPLEX*16         A( LDA, * ), C( LDC, * ), TAU( * ), WORK( * )
+*     ..
+*
+*  Purpose
+*  =======
+*
+*  ZUNML2 overwrites the general complex m-by-n matrix C with
+*
+*        Q * C  if SIDE = 'L' and TRANS = 'N', or
+*
+*        Q'* C  if SIDE = 'L' and TRANS = 'C', or
+*
+*        C * Q  if SIDE = 'R' and TRANS = 'N', or
+*
+*        C * Q' if SIDE = 'R' and TRANS = 'C',
+*
+*  where Q is a complex unitary matrix defined as the product of k
+*  elementary reflectors
+*
+*        Q = H(k)' . . . H(2)' H(1)'
+*
+*  as returned by ZGELQF. Q is of order m if SIDE = 'L' and of order n
+*  if SIDE = 'R'.
+*
+*  Arguments
+*  =========
+*
+*  SIDE    (input) CHARACTER*1
+*          = 'L': apply Q or Q' from the Left
+*          = 'R': apply Q or Q' from the Right
+*
+*  TRANS   (input) CHARACTER*1
+*          = 'N': apply Q  (No transpose)
+*          = 'C': apply Q' (Conjugate transpose)
+*
+*  M       (input) INTEGER
+*          The number of rows of the matrix C. M >= 0.
+*
+*  N       (input) INTEGER
+*          The number of columns of the matrix C. N >= 0.
+*
+*  K       (input) INTEGER
+*          The number of elementary reflectors whose product defines
+*          the matrix Q.
+*          If SIDE = 'L', M >= K >= 0;
+*          if SIDE = 'R', N >= K >= 0.
+*
+*  A       (input) COMPLEX*16 array, dimension
+*                               (LDA,M) if SIDE = 'L',
+*                               (LDA,N) if SIDE = 'R'
+*          The i-th row must contain the vector which defines the
+*          elementary reflector H(i), for i = 1,2,...,k, as returned by
+*          ZGELQF in the first k rows of its array argument A.
+*          A is modified by the routine but restored on exit.
+*
+*  LDA     (input) INTEGER
+*          The leading dimension of the array A. LDA >= max(1,K).
+*
+*  TAU     (input) COMPLEX*16 array, dimension (K)
+*          TAU(i) must contain the scalar factor of the elementary
+*          reflector H(i), as returned by ZGELQF.
+*
+*  C       (input/output) COMPLEX*16 array, dimension (LDC,N)
+*          On entry, the m-by-n matrix C.
+*          On exit, C is overwritten by Q*C or Q'*C or C*Q' or C*Q.
+*
+*  LDC     (input) INTEGER
+*          The leading dimension of the array C. LDC >= max(1,M).
+*
+*  WORK    (workspace) COMPLEX*16 array, dimension
+*                                   (N) if SIDE = 'L',
+*                                   (M) if SIDE = 'R'
+*
+*  INFO    (output) INTEGER
+*          = 0: successful exit
+*          < 0: if INFO = -i, the i-th argument had an illegal value
