Aw drat. I was going to submit the n'th prime problem until I saw this.
Sadly, I see there are too few test cases, and the problem is too easy to cook.
why 'nthprime' not allowed?
There's a really easy way to cheese this problem if you find it. It happens to lie in the comment John D'Errico made about there being too few test cases. I'd encourage you to do the problem properly without such a cheese
A good problem!

This solution doesn't use any of the built-in MATLAB functions primes() or isprime(). It works for all integers N > 0, and requires only (N^0.75) iterations.

I do not know how the size are computed. Would someone please tell me?. Thanks in advance.
See https://au.mathworks.com/matlabcentral/about/cody/#solve_problems for basic concept. The best way to figure out the details is from experience — just try different alternatives.
