By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13.
What is the Nth prime number?
Thank you to Project Euler Problem 7
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?
Another great 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.
