I tried to produce 10^6 poisson distributed random numbers and when i looked at the histogram, it had either some gaps or shoots depending upon the bin size... can anyone exlpain whats happening here?
t = zeros(1000000,1);
for i = 1:1000000
t(i,1) = poissrnd(100);
end
hist(t,300)

The loop is unnecessary:
histogram(poissrnd(100,1e6,1),300)
Works as expected.
