How do I build a labeled Tree?

I have a set of node labels (1,2,3,....) and set of pairs of nodes. How do I build a labeled tree in matlab, using this information? Thanks.

Hi,

To label the nodes in a tree or graph in MATLAB, you can utilize the labelnode function. Below is a code snippet that demonstrates how to achieve this:

s = [1 1 2 2 3 4 5 5];
t = [2 3 3 4 4 5 1 2];
G = digraph(s, t);
h = plot(G);
labelnode(h, [1:5], {'A', 'B', 'C', 'D', 'E'});

For more details, please refer to the MathWorks documentation on LabelNode: https://www.mathworks.com/help/matlab/ref/matlab.graphics.chart.primitive.graphplot.labelnode.html

Hope this helps!
