Number of terminal nodes
NB = ntnode(T)
ntnode is a tree-management utility.
NB = ntnode(T) returns the number of terminal nodes in the tree T.
The nodes are numbered from left to right and from top to bottom. The root index is 0.
% Create binary tree (tree of order 2) of depth 3. t = ntree(2,3); % Plot tree t. plot(t)
% Number of terminal nodes. ntnode(t) ans = 8
