getdescendants (biograph)

Find descendants of a node in biograph object


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.


  1. Create a biograph object.

    cm = [0 1 1 0 0;1 0 0 1 1;1 0 0 0 0;0 0 0 0 1;1 0 1 0 0];
    bg = biograph(cm)
  2. Find one generation of descendants for node 4.

    desNodes = getdescendants(bg.nodes(4));
    set(desNodes,'Color',[1 .7 .7]);

  3. Find two generations of descendants for node 4.

    desNodes = getdescendants(bg.nodes(4),2);
    set(desNodes,'Color',[.7 1 .7]);
