MATLAB: How to find the average of monte carlo simulation

monte carlo

Hi, I'm generating a poisson distribution random variable for 1000 times, here is the code i've wrote
N = 1000;
lambda = 60.21;
for i = 1:N
        r = poissrnd(lambda)
end
I will get the random variable 1000 times, what code should i write to make these 1000 random variable too add up and find the average? Please help me thanks.

You could save the r's in a vector. E.g.,
r(i) = poissrnd(lambda);
Or you could generate all of the r's at once without the loop
r = poissrnd(lambda,N,1);
and then use the mean( ) function.
