riccati_yn(n, x)

The Ricatti-Bessel function of the second kind is defined as $x y_n(x)$ , where $y_n$ is the spherical Bessel function of the second kind of order $n$ .

This function computes the value and first derivative of the function for all orders up to and including n.

Notes

The computation is carried out via ascending recurrence, using the relation DLMF 10.51.1 .

Wrapper for a Fortran routine created by Shanjie Zhang and Jianming Jin .

Parameters

n : int

Maximum order of function to compute

x : float

Argument at which to evaluate

Returns

yn : ndarray

Value of y0(x), ..., yn(x)

ynp : ndarray

First derivative y0'(x), ..., yn'(x)

Compute Ricatti-Bessel function of the second kind and its derivative.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
