SLARTV  -  applie a vector of real plane rotations to ele­
       ments of the real vectors x and y


SYNOPSIS

       SUBROUTINE SLARTV( N, X, INCX, Y, INCY, C, S, INCC )

           INTEGER        INCC, INCX, INCY, N

           REAL           C( * ), S( * ), X( * ), Y( * )


PURPOSE

       SLARTV applies a vector of real plane  rotations  to  ele­
       ments 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) )


ARGUMENTS

       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.
