Function/Subroutine Documentation

subroutine dlartv (integer N, double precision, dimension( * ) X, integer INCX, double precision, dimension( * ) Y, integer INCY, double precision, dimension( * ) C, double precision, dimension( * ) S, integer INCC)

DLARTV applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors.

Purpose:

``` DLARTV 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 DOUBLE PRECISION array,
dimension (1+(N-1)*INCX)
The vector x.```

INCX

```          INCX is INTEGER
The increment between elements of X. INCX > 0.```

Y

```          Y is DOUBLE PRECISION array,
dimension (1+(N-1)*INCY)
The vector y.```

INCY

```          INCY is INTEGER
The increment between elements of Y. INCY > 0.```

C

```          C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.```

S

```          S is DOUBLE PRECISION 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.```
