NAME
     zlar2v - apply a vector of complex plane rotations with real
     cosines from both sides to a sequence of 2-by-2 complex Her-
     mitian matrices,

SYNOPSIS
     SUBROUTINE ZLAR2V( N, X, Y, Z, INCX, C, S, INCC )

     INTEGER INCC, INCX, N

     DOUBLE PRECISION C( * )

     COMPLEX*16 S( * ), X( * ), Y( * ), Z( * )



     #include <sunperf.h>

     void zlar2v(int n,  doublecomplex  *zx,  doublecomplex  *zy,
               doublecomplex  *zz,  int  incx,  double *dc, doub-
               lecomplex *s, int incc) ;

PURPOSE
     ZLAR2V applies a vector of complex plane rotations with real
     cosines from both sides to a sequence of 2-by-2 complex Her-
     mitian matrices, defined by the elements of the vectors x, y
     and z. For i = 1,2,...,n

        (       x(i)  z(i) ) :=
        ( conjg(z(i)) y(i) )

          (  c(i) conjg(s(i)) ) (       x(i)  z(i) ) ( c(i) -conjg(s(i)) )
          ( -s(i)       c(i)  ) ( conjg(z(i)) y(i) ) ( s(i)        c(i)  )


ARGUMENTS
     N         (input) INTEGER
               The number of plane rotations to be applied.

     X         (input/output) COMPLEX*16 array, dimension  (1+(N-
               1)*INCX)
               The vector x; the elements of x are assumed to  be
               real.

     Y         (input/output) COMPLEX*16 array, dimension  (1+(N-
               1)*INCX)
               The vector y; the elements of y are assumed to  be
               real.

     Z         (input/output) COMPLEX*16 array, dimension  (1+(N-
               1)*INCX)
               The vector z.

     INCX      (input) INTEGER
               The increment between elements of X, Y and Z. INCX
               > 0.

     C         (input) DOUBLE PRECISION array,  dimension  (1+(N-
               1)*INCC)
               The cosines of the plane rotations.

     S         (input) COMPLEX*16 array, dimension (1+(N-1)*INCC)
               The sines of the plane rotations.

     INCC      (input) INTEGER
               The increment between elements of C and S. INCC  >
               0.
