SLARTV - applie a vector of real plane rotations to elements of the real
vectors x and y
SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
SUBROUTINE SLARTV( N, X, INCX, Y, INCY, C, S, INCC )
INTEGER INCC, INCX, INCY, N
REAL C( * ), S( * ), X( * ), Y( * )
PPPPUUUURRRRPPPPOOOOSSSSEEEE
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) )
AAAARRRRGGGGUUUUMMMMEEEENNNNTTTTSSSS
N (input) INTEGER
The number of plane rotations to be applied.
X (input/output) REAL array,
dimension (1+(N-1)*INCX) The vector x.
INCX (input) INTEGER
The increment between elements of X. INCX > 0.
Y (input/output) REAL 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) REAL 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.
