std::binomial_distribution::param - cppreference.com (original) (raw)

param_type param() const; (1) (since C++11)
void param( const param_type& params ); (2) (since C++11)

Manages the associated distribution parameter set.

  1. Returns the associated parameter set.

  2. Sets the associated parameter set to params.

[edit] Parameters

params - new contents of the associated parameter set

[edit] Return value

  1. The associated parameter set.

  2. (none)

[edit] Complexity

Constant.

[edit] Example

#include #include   int main() { std::random_device rd; std::mt19937 gen(rd()); using BinomialDist = std::binomial_distribution<>; BinomialDist bino_dis(1, 0.5);   std::cout << "A sample of Binomial( 1, 0.5): " << bino_dis(gen) << '\n';   // Use another parameter set bino_dis.param(BinomialDist::param_type(100,0.9)); std::cout << "A sample of Binomial(100, 0.9): " << bino_dis(gen) << '\n'; }

Possible output:

A sample of Binomial( 1, 0.5): 0 A sample of Binomial(100, 0.9): 94
