std::discrete_distribution<IntType>::probabilities: std::discrete_distribution<IntType>::probabilities

NAME

std::discrete_distribution<IntType>::probabilities - std::discrete_distribution<IntType>::probabilities

Synopsis

std::vector<double> probabilities() const; (since C++11)

Obtains a std::vector<double> containing the individual probabilities of each integer that is generated by this distribution.

Parameters

(none)

Return value

An object of type std::vector<double>

Example

// Run this code

  #include <iostream>
  #include <vector>
  #include <random>
  int main()
  {
      std::discrete_distribution<> d({40, 10, 10, 40});
      std::vector<double> p = d.probabilities();
      for(auto n : p)
          std::cout << n << ' ';
      std::cout << '\n';
  }

Output:

  0.4 0.1 0.1 0.4
