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 ]
