D. G. Gordeev, A. L Lomaykin VANT. Ser.: Mat. Mod. Fiz. Proc 2008. Вып.1. С. 42-50.
The paper presents results of fitting and realization of approximation expression for Debye D3(x) function in 0 ≤ x < ∞ domain. Approximation provides continuity up to and including the second derivative and computation time acceptable for application programs.
