subroutine slartv (integerN, real, dimension( * )X, integerINCX, real, dimension( * )Y, integerINCY, real, dimension( * )C, real, dimension( * )S, integerINCC)¶
SLARTV 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) )

N is INTEGER The number of plane rotations to be applied.
X is REAL array, dimension (1+(N-1)*INCX) The vector x.
INCX is INTEGER The increment between elements of X. INCX > 0.
Y is REAL array, dimension (1+(N-1)*INCY) The vector y.
INCY is INTEGER The increment between elements of Y. INCY > 0.
C is REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations.
S is REAL array, dimension (1+(N-1)*INCC) The sines of the plane rotations.
INCC is INTEGER The increment between elements of C and S. INCC > 0.
