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

INCX |
(input) INTEGER
The increment between elements of X. INCX > 0.
|
Y |
(input/output) REAL array,
dimension (1+(N-1)*INCY)
