subroutine zlacrt (N, CX, INCX, CY, INCY, C, S)
subroutine zlacrt (integerN, complex*16, dimension( * )CX, integerINCX, complex*16, dimension( * )CY, integerINCY, complex*16C, complex*16S)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.
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*16S
S is COMPLEX*16 C and S define the matrix [ C S ]. [ -S C ]
