allnodes
Purpose
Tree nodes
Syntax
Description
allnodes is a tree management utility that returns one of two node descriptions: either indices, or depths and positions.
The nodes are numbered from left to right and from top to bottom. The root index is 0.
N = allnodes(T) returns the indices of all the nodes of the tree T in column vector N.
N = allnodes(T,'deppos') returns the depths and positions of all the nodes in matrix N.
N(i,1) is the depth and N(i,2) the position of the node i.
Examples
% Create initial tree.
ord = 2;
t = ntree(ord,3); % Binary tree of depth 3.
t = nodejoin(t,5);
t = nodejoin(t,4);
plot(t)
% Change Node Label from Depth_Position to Index
% (see the plot function).
% List t nodes (index).
aln_ind = allnodes(t)
