ifht(A, dln, mu, offset=0.0, bias=0.0)

Computes the discrete inverse Hankel transform of a logarithmically spaced periodic sequence. This is the inverse operation to fht .

Notes

This function computes a discrete version of the Hankel transform

$$a(r) = \int_{0}^{\infty} \! A(k) \, J_\mu(kr) \, r \, dk \;,$$

where $J_\mu$ is the Bessel function of order $\mu$ . The index $\mu$ may be any real number, positive or negative.

See fht for further details.

Parameters

A : array_like (..., n)

Real periodic input array, uniformly logarithmically spaced. For multidimensional input, the transform is performed over the last axis.

dln : float

Uniform logarithmic spacing of the input array.

mu : float

Order of the Hankel transform, any positive or negative real number.

offset : float, optional

Offset of the uniform logarithmic spacing of the output array.

bias : float, optional

Exponent of power law bias, any positive or negative real number.

Returns

a : array_like (..., n)

The transformed output array, which is real, periodic, uniformly logarithmically spaced, and of the same shape as the input array.

Compute the inverse fast Hankel transform.

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
