Function Documentation

binomial()

template<typename T = unsigned int>

constexpr T TPCC::binomial ( T  n, T  k  )

constexpr

Compute the binomial coefficient n over k.

This function is constexpr, such that it can be eliminated completely if #n and #k are known at compile time.

compute_complement()

template<typename T = unsigned int, T n, T k>

constexpr std::array<T, n - k> TPCC::compute_complement ( std::array< T, k >  combi )

constexpr

Given a combination as an array, compute its complement in the set of numbers from 0 to n-1.

Todo:

Make this constexpr
