Function/Subroutine Documentation
subroutine slartv (integerN, real, dimension( * )X, integerINCX, real,
dimension( * )Y, integerINCY, real, dimension( * )C, real, dimension( *
)S, integerINCC)
SLARTV applies a vector of plane rotations with real cosines and real
sines to the elements of a pair of vectors.
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) )
Parameters:
N
N is INTEGER
The number of plane rotations to be applied.
X
X is REAL array,
dimension (1+(N-1)*INCX)
The vector x.
INCX
INCX is INTEGER
The increment between elements of X. INCX > 0.
Y
Y is REAL array,
dimension (1+(N-1)*INCY)
The vector y.
INCY
INCY is INTEGER
The increment between elements of Y. INCY > 0.
C
C is REAL array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
S
S is REAL array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.
INCC
INCC is INTEGER
The increment between elements of C and S. INCC > 0.
