Calculating how many runs die out

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
