NAME
     clar2v - 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 CLAR2V( N, X, Y, Z, INCX, C, S, INCC )

     INTEGER INCC, INCX, N

     REAL C( * )

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



     #include <sunperf.h>

     void clar2v(int n, complex *cx, complex  *cy,  complex  *cz,
               int incx, float *sc, complex *s, int incc) ;

PURPOSE
     CLAR2V 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  array,  dimension  (1+(N-
               1)*INCX)
               The vector x; the elements of x are assumed to  be
               real.

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

     Z         (input/output)  COMPLEX  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) REAL array, dimension (1+(N-1)*INCC)
               The cosines of the plane rotations.

     S         (input) COMPLEX 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.
