CLACRT
November 2006
Purpose
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.
( c s )( x ) ==> ( x )
( -s c )( y ) ( y )
where c and s are complex and the vectors x and y are complex.
Arguments
| N |
(input) INTEGER
The number of elements in the vectors CX and CY.
|
| CX |
(input/output) COMPLEX 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 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
|
| S |
(input) COMPLEX
C and S define the matrix
[ C S ]. [ -S C ] |
