find node with maximum degree

Hello !!

I have nodes 1 to 30 with degree

node = [ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30]

degre = [ 11 11 12 10 15 10 8 14 12 1 8 6 2 18 5 3 7 4 15 2 0 0 0 0 0 0 0 0 0 0 ]

how to find node with maximum degree and label it xi .?

i tried using [B,I] = maxk(deg,node); but it doesn't work. because the degree value is always changing

should node 14 with degree 18 be labeled 1 and ect, until all nodes are labeled

thank you

If you want to get the values from the arrays -

node=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30];
degree=[11 11 12 10 15 10 8 14 12 1 8 6 2 18 5 3 7 4 15 2 0 0 0 0 0 0 0 0 0 0];
[degmax,idx]=max(degree)

degmax = 18

idx = 14

node(idx)

ans = 14

thank for the anwers Dyuman joshi

but, how can i check all the nodes by degree using loop and label them according to the highest to lowest degree.

exp

node = [ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 ]

degre = [ 11 11 12 10 15 10 8 14 12 1 8 6 2 18 5 ]

label = [6 7 4 8 2 9 10 3 5 10 11 12 14 1 15 ]

Your "label" seems incorrect.

node=[1 2 3 4 5 6 7 8 9 10 11 12 13 14 15];
degree=[11 11 12 10 15 10 8 14 12 1 8 6 2 18 5];
deg=unique(degree,'stable'); %for comparing individual elements
z=zeros(size(degree)); %pre-allocating array
y=sort(degree,'descend'); %sorting descendingly, to get highest-to-lowest
for i=1:numel(deg)
    z(degree==deg(i))=find(y==deg(i));
end
z

z = 1×15

6 7 4 8 2 9 10 3 5 15 11 12 14 1 13
