getancestors (biograph) - Find ancestors in biograph object

Syntax

Nodes = getancestors(BiographNode)
Nodes = getancestors(BiographNode, NumGenerations)

Arguments

BiographNode	Node in a biograph object.
NumGenerations	Number of generations. Enter a positive integer.

Description

Nodes = getancestors(BiographNode) returns a node (BiographNode) and all of its direct ancestors.

Nodes = getancestors(BiographNode, NumGenerations) finds the node (BiographNode) and its direct ancestors up to a specified number of generations (NumGenerations).

Examples

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 ancestors for node 2.

   ancNodes = getancestors(bg.nodes(2));
   set(ancNodes,'Color',[1 .7 .7]);
   bg.view;
   

   

   
   

3. Find two generations of ancestors for node 2.

   ancNodes = getancestors(bg.nodes(2),2);
   set(ancNodes,'Color',[.7 1 .7]);
   bg.view;
