This is a fast prime number list generator using sieve algorithm. This function return a list of prime numbers which <= argument.
primepow(aNumber) finds the prime number P and power N of aNumber such that aNumber = P^N.
The implementation is heavily borrowed from Art Owen <a href="http://www.csit.fsu.edu/~burkardt/cpp_src/oa/oa.html">Orthogonal...
Lightweight prime number generation library. Makes use of OpenMP and aims for performance. Suitable for applications in cryptography or just for educational demonstration.
The algorithm is based on the idea
that the next larger prime after one prime is the sum of the two smaller previous minus three prime numbers back.
For the first five prime numbers 2,3,5,7,11 this pattern is not true also it is not...
This program implements primality testing function.
The function is then used to generate prime numbers
in the given range.
Since the excellent <a href="http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/366178">fast prime number list generator</a> recipe, it's simple to implement a function to check if its input it's a prime number.
Using python 2.6 & numpy.

p : odd prime number
deg: positive integer (default value = 1)
Output is a (p^deg+1) by (p^deg+1)/2 matrix E
When deg > 1, the communication toolbox is required

A one-liner that returns the list of prime numbers up to n. The inner lambda is the sieve.
Uses an array to store the values, expands the size of the prime list on the fly, you can make a guess at how many you will need.
I am finding it useful for the problems at http://projecteuler.net
Any thoughts for improvement appreciated...

We are however, limited in the range here because MATLAB's isprime()is limited to only 2^32.

This is an evolutionary algorithm that returns a random list of prime numbers. This code is highly inefficient for a reason. This algorithm is more of a proof of concept that if a prime was a heritable trait, it would not be a desired one.
Basic idea was to see the difference between different prime algorithms in time. Also they are not perfect the output shows that really higher numbers let grow the difference why I have separated this into functions to make it visible. I add this...
A class Ive had in my snippets for awhile that can generate prime, perfect and fibonacci sequences as well as check whether or not a supplied value is any of them.
Very rarely it is necessary to find the multiplicative inverse of a number in the ring of integers modulo p. Thie recipe handles those rare cases. That is, given x, an integer, and p the modulus, we seek a integer x^-1 such that x * x^-1 = 1 mod...
