+*  Purpose
+*  =======
+*
+*  ZLACGV conjugates a complex vector of length N.
+*
+*  Arguments
+*  =========
+*
+*  N       (input) INTEGER
+*          The length of the vector X.  N >= 0.
+*
+*  X       (input/output) COMPLEX*16 array, dimension
+*                         (1+(N-1)*abs(INCX))
+*          On entry, the vector of length N to be conjugated.
+*          On exit, X is overwritten with conjg(X).
+*
+*  INCX    (input) INTEGER
+*          The spacing between successive elements of X.
