ntnode

R2026b

Number of terminal nodes

Syntax

nb = ntnode(t)

Description

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.

Examples

Count Terminal Nodes

Create a tree of order 3 and depth 2.

t = ntree(3,2);

Plot the tree.

plot(t)

Use the ntnode function to count the terminal nodes.

nb = ntnode(t)

nb = 
9

Input Arguments

t — Tree

ntree object | dtree object | wptree object

Tree, specified as an ntree, dtree, or wptree object.

Extended Capabilities

Thread-Based Environment

Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.
