Implementation of the probability distribution function for random flights in 3D.
This is a header-only C++ library: Merely include RandomFlightPDF.hpp into your C++ project and you have access to RandomFlight::PDF. The latter is a function object. Simply intitialize it with the number n of steps:
RandomFlight::PDF F (n);
Then F is an instance of this function class. Then call F on an arbitrary value real t":
double result = F(t);
That's it. You may also have a look at the usage example Example/main.cpp. For example, with clang you can compile it from the terminal with
clang main.cpp -Wall -std=c++20 -lstdc++ -Ofast -o ./main.out
and then run
./main.out
That's it!
