NAME
       SRC/crot.f

SYNOPSIS
   Functions/Subroutines
       subroutine crot (n, cx, incx, cy, incy, c, s)
           CROT applies a plane rotation with real cosine and complex sine to
           a pair of complex vectors.

Function/Subroutine Documentation
   subroutine crot (integer n, complex, dimension( * ) cx, integer incx,
       complex, dimension( * ) cy, integer incy, real c, complex s)
       CROT applies a plane rotation with real cosine and complex sine to a
       pair of complex vectors.

       Purpose:


           !>
           !> CROT applies a plane rotation, where the cos (C) is real and the
           !> sin (S) is complex, and the vectors CX and CY are complex.
           !>

       Parameters
           N

           !>          N is INTEGER
           !>          The number of elements in the vectors CX and CY.
           !>

           CX

           !>          CX is COMPLEX array, dimension (N)
           !>          On input, the vector X.
           !>          On output, CX is overwritten with C*X + S*Y.
           !>

           INCX

           !>          INCX is INTEGER
           !>          The increment between successive values of CX.  INCX <> 0.
           !>

           CY

           !>          CY is COMPLEX array, dimension (N)
           !>          On input, the vector Y.
           !>          On output, CY is overwritten with -CONJG(S)*X + C*Y.
           !>

           INCY

           !>          INCY is INTEGER
           !>          The increment between successive values of CY.  INCX <> 0.
           !>

           C

           !>          C is REAL
           !>

           S

           !>          S is COMPLEX
           !>          C and S define a rotation
           !>             [  C          S  ]
           !>             [ -conjg(S)   C  ]
           !>          where C*C + S*CONJG(S) = 1.0.
