error in digraph while finding adjacency matrix

i get this error while finding adjacency matrix Error using digraph/adjacency Too many input arguments. hers the simple code s = [1 2 5 7 1 3 6 8 2 4 3 4 6];

t = [2 5 7 9 3 6 8 9 4 6 4 5 7];

W=[1 2 3 4 1 2 3 4 2 3 2 3 3];

names = {'S' 'A' 'B' 'C' 'E' 'F' 'G' 'H' 'D'};

G = digraph(s,t,W,names);

A=adjacency(G,'weights')

s=plot(G,'layout','force','Edgelabel',G.Edges.Weight);

B = full(A)

Answer 1

The optional second input argument of adjacency was introduced in R2018a. Since you get a too many input arguments error when giving a second input we can safely conclude that you're using an earlier version.

You should look at the documentation that comes with your version.

doc digraph.adjacency

at matlab command prompt to look at your documentation.

Note that the proper syntax in R2018a or later is

adjacency(G,'weighted')  %not 'weights'

Hi,

try:

s = [1 2 5 7 1 3 6 8 2 4 3 4 6];
t = [2 5 7 9 3 6 8 9 4 6 4 5 7];
W=[1 2 3 4 1 2 3 4 2 3 2 3 3];
names = {'S' 'A' 'B' 'C' 'E' 'F' 'G' 'H' 'D'};
G = digraph(s,t,W,names);
A=adjacency(G,W)
s=plot(G,'layout','force','Edgelabel',G.Edges.Weight);
B = full(A)

Best regards

Stephan

thank you so much for replying Mr.Stephan..But still I get the same Error

"Error using digraph/adjacency Too many input arguments.

Error in grapp (line 6) A=adjacency(G,W)
