NAME
       zlacrt.f -

SYNOPSIS
   Functions/Subroutines
       subroutine zlacrt (N, CX, INCX, CY, INCY, C, S)
	   ZLACRT

Function/Subroutine Documentation
   subroutine zlacrt (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, complex*16C, complex*16S)
       ZLACRT

       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  ]
