伯努利反功率系列软件

Function converts an ordinary power series into a power series of weighted Bernoulli polynomials, or vice versa.

软件应用简介

Inverse: Function output c is the ordinary coefficient vector, real-valued . Function input d is the Bernoulli coefficient vector, real-valued. Use row vectors.

c = inverse_bernoulli_power_series(d)

Thorough theory can be found here. Methodology relies on definition of Bernoulli polynomials via inverted Dirichlet series.

Quick explanation

Define an ordinary power series, where c_k | k=0,1,2… denotes the ordinary coefficient vector

y(x) = c_0 + xc_1 + x^2c_2…

Define a Bernoulli power series , where d_k | k=0,1,2… denotes the Bernoulli coefficient vector

y(x) = B_0(x)d_0 + B_1(x)d_1 + B_2(x)d_2…
