std::piecew...distribution(3)

💖 NAME 💖

std::piecewise_constant_distribution::piecewise_constant_distribution - std::piecewise_constant_distribution::piecewise_constant_distribution — okay bestie, yes, it's the same iconic name twice 😭👑. This is the std::piecew...distribution(3) page from the C++ Standard Libary, and it's literally all about the constructor for std::piecewise_constant_distribution.

✨ Synopsis ✨

Deep breath, bestie — here's the whole constructor lineup, every one of them since C++11:

piecewise_constant_distribution();
(1) (since C++11)

template< class InputIt1, class InputIt2 >
piecewise_constant_distribution( InputIt1 first_i, InputIt1 last_i,
                                 InputIt2 first_w );
(2) (since C++11)

template< class UnaryOperation >
piecewise_constant_distribution( std::initializer_list<RealType> ilist_i,
                                 UnaryOperation fw );
(3) (since C++11)

template< class UnaryOperation >
piecewise_constant_distribution( std::size_t nw,
                                 RealType xmin, RealType xmax,
                                 UnaryOperation fw );
(4) (since C++11)

explicit piecewise_constant_distribution( const param_type& param );
(5) (since C++11)

Constructs new piecewise constant distribution object 💅. No cap, that's the whole mood. Here's the vibe check for each one:

1. Constructs a distribution object with n = 1, ρ0 = 1, b0 = 0, and b1 = 1 🌱.
2. Constructs a distribution object from iterators over the interval sequence [first_i, last_i) and a matching weight sequence starting at first_w 🫶.
3. Constructs a distribution object where the intervals are taken from the initializer list ilist_i and the weights generated by the function fw 🌸.
4. Constructs a distribution object with the nw intervals distributed uniformly over [xmin, xmax] and the weights generated by the function fw 🔥.
5. Constructs a distribution object initialized with the parameters param 🎀.

🎀 Parameters 🎀

• first_i — iterator initialized to the start of the interval sequence 🫶
• last_i — iterator initialized to one-past-the-end of the interval sequence ✨
• first_w — iterator initialized to the start of the density (weight) sequence 💅
• ilist_i — initializer_list yielding the interval sequence 🌸
• fw — double(double) function yielding the densities 🔥
• nw — the number of densities ⭐
• xmin — the lower bound of the interval sequence 💜
• xmax — the upper bound of the interval sequence 🦋
• param — the distribution parameter set 🎀

okay bestie, that's the whole page, and it ate 💖. source/version: http://cppreference.com 🌈, date: 2024.06.10 👑. periodt.
