Crate complex_bessel 

Pure Rust implementation of complex Bessel functions based on Amos Algorithm 644 (TOMS 644).

This crate provides complex-valued Bessel functions of the first kind (J), second kind (Y), modified first kind (I), modified second kind (K), Hankel functions (H), and Airy functions (Ai, Bi).

Status

This crate is in early development (alpha). Function signatures are defined but implementations are not yet available.
