Bessel-Related Functions
Using original algorithms developed at Wolfram Research, the Wolfram Language has full coverage of all standard Bessel-related functions—evaluating every function to arbitrary precision with optimized algorithms for arbitrary complex values of its parameters, as well as supporting series and asymptotic expansions with full treatment of Stokes sectors, and an extensive web of symbolic transformations and simplifications.
