## Synopsis

### Functions/Subroutines

subroutine **dlargv** (**N**, X, INCX, Y, INCY, C, INCC)**DLARGV** generates a vector of plane rotations with real cosines and real sines.

## Function/Subroutine Documentation

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

**DLARGV** generates a vector of plane rotations with real cosines and real sines.

**Purpose:**

DLARGV generates a vector of real plane rotations, determined by elements of the real vectors x and y. For i = 1,2,...,n ( c(i) s(i) ) ( x(i) ) = ( a(i) ) ( -s(i) c(i) ) ( y(i) ) = ( 0 )

**Parameters:***N*N is INTEGER The number of plane rotations to be generated.

*X*X is DOUBLE PRECISION array, dimension (1+(N-1)*INCX) On entry, the vector x. On exit, x(i) is overwritten by a(i), for i = 1,...,n.

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

*Y*Y is DOUBLE PRECISION array, dimension (1+(N-1)*INCY) On entry, the vector y. On exit, the sines of the plane rotations.

*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.

*INCC*INCC is INTEGER The increment between elements of C. INCC > 0.
