NAME
       clacrt.f -

SYNOPSIS
   Functions/Subroutines
       subroutine clacrt (N, CX, INCX, CY, INCY, C, S)
           CLACRT performs a linear transformation of a pair of complex
           vectors.

Function/Subroutine Documentation
   subroutine clacrt (integerN, complex, dimension( * )CX, integerINCX,
       complex, dimension( * )CY, integerINCY, complexC, complexS)
       CLACRT performs a linear transformation of a pair of complex vectors.

       Purpose:

            CLACRT performs the operation

               (  c  s )( x )  ==> ( x )
               ( -s  c )( y )      ( y )

            where c and s are complex and the vectors x and y 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 -s*x + c*y.

           INCY

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

           C

                     C is COMPLEX

           S

                     S is COMPLEX
                     C and S define the matrix
                        [  C   S  ].
                        [ -S   C  ]
