public class Dlargv
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

 *     ..
 *
 *  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  )
 *
 *  Arguments
 *  =========
 *
 *  N       (input) INTEGER
 *          The number of plane rotations to be generated.
 *
 *  X       (input/output) 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    (input) INTEGER
 *          The increment between elements of X. INCX > 0.
 *
 *  Y       (input/output) DOUBLE PRECISION array,
 *                         dimension (1+(N-1)*INCY)
 *          On entry, the vector y.
 *          On exit, the sines of the plane rotations.
 *
 *  INCY    (input) INTEGER
 *          The increment between elements of Y. INCY > 0.
 *
 *  C       (output) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
 *          The cosines of the plane rotations.
 *
 *  INCC    (input) INTEGER
 *          The increment between elements of C. INCC > 0.
