Returns the the backwards differencing coefficients.
Backward differentiation formula of order \(k+1\) is given by
\begin{align*} \frac{d}{d x}f(x)\big|_{x_i} = \frac{1}{h}\sum^{k+1}_{l=0} c_l\, f(x_{i-l}) \end{align*}
The weights are related to the poly_differentiation
weights.
bd_weights
returns the coefficient \(c_l\) for given \(l\).
