getdescendants (biograph)

(To be removed) Find descendants of a node in biograph object

getdescendants (biograph) will be removed in a future release. Use successors instead. Note that the function does not let you specify NumGenerations. You can use distances to find the distances from all nodes to the target node after setting the edge weight to 1, and filter the nodes by distance to the appropriate depth.


Nodes = getdescendants(BiographNode)
Nodes = getdescendants(BiographNode,NumGenerations)



Node in a biograph object.


Number of generations. Enter a positive integer.


Nodes = getdescendants(BiographNode) finds a given node (BiographNode) all of its direct descendants.

Nodes = getdescendants(BiographNode,NumGenerations) finds the node (BiographNode) and all of its direct descendants up to a specified number of generations (NumGenerations). If the NumGenerations is 0, the function returns the node itself.
