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.
