I was working with following code to plot and it shows the error 'Adjacency matrix must be square'
clear all
close all
clc
K=[0 0 0 0 1 , 0 0 0 0 2 , 0 0 0 0 3, 0 0 0 0 4 , 0 0 0 0 5 , 0 0 0 0 0];
nodes= ['A', 'B' , 'C' , 'D' , 'E' , 'F'];
G = digraph(K,nodes);
plot(G,'Layout','circle')

In your assignment to K, change the commas into semi-colon
K=[0 0 0 0 1 ; 0 0 0 0 2 ; 0 0 0 0 3; 0 0 0 0 4 ; 0 0 0 0 5 ; 0 0 0 0 0];

Thank you so much Walter Roberson for answering. when i tried with semicolon and run the code it shows as same error Adjacency matrix must be square, then i tried using (.^2) operator in the code as shown below clear all close all clc K=[0 0 0 0 1 ; 0 0 0 0 2 ; 0 0 0 0 3 ; 0 0 0 0 4 ; 0 0 0 0 5 ; 0 0 0 0 0]; nodes= ['A', 'B' , 'C' , 'D' , 'E' , 'F']; G = digraph(K,nodes.^2); plot(G,'Layout','circle') title('STAR TOPOLOGY')
when i run this code it shows the error as follows Error in digraph (line 247) matlab.internal.graph.constructFromEdgeList( ... How to fix it?...
