NAME
       SRC/zlacrt.f

SYNOPSIS
   Functions/Subroutines
       subroutine zlacrt (n, cx, incx, cy, incy, c, s)
           ZLACRT performs a linear transformation of a pair of complex
           vectors.

Function/Subroutine Documentation
   subroutine zlacrt (integer n, complex*16, dimension( * ) cx, integer incx,
       complex*16, dimension( * ) cy, integer incy, complex*16 c, complex*16
       s)
       ZLACRT performs a linear transformation of a pair of complex vectors.

       Purpose:


            ZLACRT 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*16 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*16 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*16

           S

                     S is COMPLEX*16
                     C and S define the matrix
                        [  C   S  ].
                        [ -S   C  ]
