_fromroots(line_f, mul_f, roots)

Parameters

line_f : function(float, float) -> ndarray

The <type>line function, such as polyline

mul_f : function(array_like, array_like) -> ndarray

The <type>mul function, such as polymul

roots :

See the <type>fromroots functions for more detail

Helper function used to implement the <type>fromroots functions.

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
