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.
