Landmark.distance

Landmark.distance(coord: ArrayLike | Vertex) → float

Distance from vertex to point

Parameters:

coord (ndarray(n) or Vertex) – coordinates of the point

Returns:

distance

Return type:

float

Distance is computed according to the graph’s metric. The vertex must belong to a graph, since the metric is a property of the graph, not the vertex.

>>> from pgraph import UGraph
>>> g = UGraph()
>>> v1 = g.add_vertex(coord=[0,0], name='v1')
>>> v2 = g.add_vertex(coord=[3,4], name='v2')
>>> print(v1.distance(v2))
5.0
