[−][src]Module helixiser::bessel_utils
collection of bessel functions
The approaches to compute the functions below are probably not optimal. I would be hesitant to recommend these these functions for your own project.
Functions
| J0 | Computes J0(x) ( bessel function of the first kind of zeroth order ) |
| J0a | Computes J0(x), for small values of x |
| J0b | Computes J0(x), for large values of x |
| J1 | Computes J1(x) ( bessel function of the first kind of first order ) |
| J1a | Computes J1(x), for small values of x |
| J1b | Computes J1(x), for large values of x |
| Jn | computes the value of Jn(x) for given n and x |
| bessel_first_max | get x value of the first maximum of Jn(x) for given n. |
| nextBessel | computes the next bessel "Jn(x)" using the values of Jn_minus_one(x) and Jn_minus_two(x) (at same x) |
