CLACRT performs a linear transformation of a pair of complex vectors.
Function/Subroutine Documentation
subroutine clacrt (integerN, complex, dimension( * )CX, integerINCX, complex, dimension( *
)CY, integerINCY, complexC, complexS)
CLACRT performs a linear transformation of a pair of complex vectors.
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.
Parameters:
N
N is INTEGER
The number of elements in the vectors CX and CY.
CX
CX is COMPLEX 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 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
S
S is COMPLEX
C and S define the matrix
[ C S ].
[ S C ]
