getancestors (biograph)
Find ancestors of a node in biograph object
Syntax
Node = getancestors(BiographNode)
Node = getancestors(BiographNode,
NumGenerations)
Arguments
| Node in a biograph object. |
| Number of generations. Enter a positive integer. |
Description
Node = getancestors(BiographNode)BiographNode) and all of its direct ancestors.
Node = getancestors(BiographNode,
NumGenerations)BiographNode)
and its direct ancestors up to a specified number of generations (NumGenerations).
If NumGenerations is 0,
the function returns the node itself.
Examples
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)
Find one generation of ancestors for node 2.
ancNodes = getancestors(bg.nodes(2)); set(ancNodes,'Color',[1 .7 .7]); bg.view;
Find two generations of ancestors for node 2.
ancNodes = getancestors(bg.nodes(2),2); set(ancNodes,'Color',[.7 1 .7]); bg.view;
