clc;
clear all;
tr=tree('root');
[tr,NYT1]=tr.addnode(1,'0');
[tr,n1]=tr.addnode(1,'node1');
I am trying to check if node1 is present in 'tr' tree or not? I tried to use and 'isfield' they don't seem to work. Here is how I used them
isfield(tr.Node,'node(1).data')
it does not seem to recognize its presence, can anyone help? thanks.

Samuel - is the tree class (?) something that you have written, is built-in to MATLAB, or from the File Exchange? Please provide a reference to this code.
