CLARTV
November 2006
Purpose
CLARTV applies a vector of complex plane rotations with real cosines
to elements of the complex vectors x and y. For i = 1,2,...,n
( x(i) ) := ( c(i) s(i) ) ( x(i) )
( y(i) ) ( -conjg(s(i)) c(i) ) ( y(i) )
to elements of the complex vectors x and y. For i = 1,2,...,n
( x(i) ) := ( c(i) s(i) ) ( x(i) )
( y(i) ) ( -conjg(s(i)) c(i) ) ( y(i) )
Arguments

|
| X |
(input/output) COMPLEX array, dimension (1+(N-1)*INCX)
The vector x.
|
| INCX |
(input) INTEGER
The increment between elements of X. INCX > 0.
|
| Y |
(input/output) COMPLEX array, dimension (1+(N-1)*INCY)
The vector y.
|
| INCY |
(input) INTEGER
The increment between elements of Y. INCY > 0.
|
| C |
(input) REAL array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
|
| S |
(input) COMPLEX array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.
|
| INCC |
(input) INTEGER
The increment between elements of C and S. INCC > 0.
