SYNOPSIS

   Functions/Subroutines

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

Function/Subroutine Documentation

   subroutine dlargv (integerN, double precision, dimension( * )X, integerINCX, double precision,
       dimension( * )Y, integerINCY, double precision, dimension( * )C, integerINCC)
       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.
