factors

MATLAB factor function

Performs prime factorization.

factors(n)

`n`	numeric scalar specifying composite number to be factored

Computes the prime factors of n in ascending order, each one as often as its multiplicity requires, such that n == prod(factors(n)).

Returns vector containing the prime factors of n.

The corresponding MATLAB function is called 'factor', but was renamed here to avoid conflict with R's compound object class.

factors(1002001)       # 7  7  11  11  13  13
factors(65537)         # is prime
## Euler's calculation
factors(2^32 + 1)      # 641  6700417
