gr_bessel_j_jet
Synopsis
#include <flint/gr_special.h>Sets res to the first len Taylor coefficients of J_\nu(z + t) at t = 0, that is, J_\nu^{(k)}(z) / k! for 0 \le k < \mathit{len} (the jet of J_\nu at z). This is a generic function, not a method: it computes J_\nu(z) and J_{\nu+1}(z) and then the higher coefficients by a three-term recurrence (https://fungrim.org/entry/9b2f38/), and uses the series expansion at z = 0 for integer \nu.
