order_angles_golden_ratio(theta)

Notes

The method used here is that of the golden ratio introduced by T. Kohler.

Parameters

theta : 1D array of floats

Projection angles in degrees. Duplicate angles are not allowed.

Returns

indices_generator : generator yielding unsigned integers

The returned generator yields indices into theta such that theta[indices] gives the approximate golden ratio ordering of the projections. In total, len(theta) indices are yielded. All non-negative integers < len(theta) are yielded exactly once.

Order angles to reduce the amount of correlated information in subsequent projections.

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
