I want to calculate how many runs die out out of k amount of runs. This doesn't work. How can i make it so the amount of runs dying out a vector where its 1 when it dies out or 0 when it doesnt?

A=createsrandomnetwork(10,1);
I=zeros(10,1);
positions=[1,1];
I(positions)=1;
v=zeros(1,10);        %Vector which proportion value will be saved into
n=numel(I);           %n=number of array elements
for k=1:10
      dieout=zeros(10,k);
for i=1:10
a = rand(10);
R = triu(a) + triu(a,1)';
H=R>0.1;     %Matrix with % chance of passing on infection
P=A.*H;      %New Network Matrix including the probability
P(logical(eye(size(P)))) = 0; %makes sure the diagonal is 0 then people can recover
I=P*I;      %New Network Matrix times the Vector of Infected   
v(i)=nnz(I)/n        %Proportion infected at time i
if sum(I)==0
     dieout(k)=1
     break
end 
end
end
