## 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.
