CLACRT(1) LAPACK auxiliary routine (version 3.2) CLACRT(1)

NAME

CLACRT - 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

SYNOPSIS

N, CX, INCX, CY, INCY, C, S )

INTEGER INCX, INCY, N COMPLEX C, S COMPLEX CX( * ), CY( * )

PURPOSE

CLACRT performs the operation

ARGUMENTS

The number of elements in the vectors CX and CY.
On input, the vector x. On output, CX is overwritten with c*x + s*y.
The increment between successive values of CX. INCX <> 0.
On input, the vector y. On output, CY is overwritten with -s*x + c*y.
The increment between successive values of CY. INCY <> 0.
S (input) COMPLEX C and S define the matrix [ C S ]. [ -S C ]
