You are using a simple rejection sampler with two conditions a > 10 & a < 10.2 a+ b > 15 However, the chance of matching both of them is low, i.e. very slow. However, since you are interested in exponential random numbers, we can avoid simulating numbers we would...

At 36 values, you have a very small sample set. From the second sentence of Wikipedia's article on the chi-squared test (emphasis added): It is suitable for unpaired data from large samples. Large in this case usually means around at least 100. Read about more assumptions of this test here....

You've got a couple of choices. In MATLAB, you can generate all samples in advance (i.e. before running the simulation) and use them to create a suitable signal, then use that as an input into the model (using the From Workspace block). Or, if you need to do the sampling...

It's not an error to get zero. With exponential interarrival times and a rate of 3 per hour, the number of occurrences in an hour has a Poisson distribution with λ=3. The probability of getting n outcomes is e-λλn/n! which for n=0 is just under 0.05. In other words, you...
