SYNOPSIS

  Functions/Subroutines
subroutine dscal (n, da, dx, incx)
DSCAL

Function/Subroutine Documentation

  subroutine dscal (integer n, double precision da, double precision, dimension(*) dx, integer incx)

DSCAL

Purpose:

    !>
    !>    DSCAL scales a vector by a constant.
    !>    uses unrolled loops for increment equal to 1.
    !>

Parameters
    N

    !>          N is INTEGER
    !>         number of elements in input vector(s)
    !>

    DA

    !>          DA is DOUBLE PRECISION
    !>           On entry, DA specifies the scalar alpha.
    !>

    DX

    !>          DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
    !>

    INCX

    !>          INCX is INTEGER
    !>         storage spacing between elements of DX
