NAME
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 complexSYNOPSIS
- SUBROUTINE ZLACRT(
- N, CX, INCX, CY, INCY, C, S )
- INTEGER INCX, INCY, N
- COMPLEX*16 C, S
- COMPLEX*16 CX( * ), CY( * )
PURPOSE
ZLACRT performs the operationARGUMENTS
- N (input) INTEGER
- The number of elements in the vectors CX and CY.
- CX (input/output) COMPLEX*16 array, dimension (N)
- On input, the vector x. On output, CX is overwritten with c*x + s*y.
- INCX (input) INTEGER
- The increment between successive values of CX. INCX <> 0.
- CY (input/output) COMPLEX*16 array, dimension (N)
- On input, the vector y. On output, CY is overwritten with -s*x + c*y.
- INCY (input) INTEGER
- The increment between successive values of CY. INCY <> 0.
- C (input) COMPLEX*16
- S (input) COMPLEX*16 C and S define the matrix [ C S ]. [ -S C ]
