std::discrete_distribution
Member functions
Generation
Characteristics
discrete_distribution::probabilities
Non-member functions
(C++11)(C++11)(until C++20)
(C++11)(C++11)
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.
[edit] Parameters
(none)
[edit] Return value
An object of type std::vector <double>.
[edit] Example
Run this code
#include <iostream> #include <random> #include <vector> 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
