C++: generate gaussian distribution

Question

Hi,

I would like to know if in C++ standard libraries there is any gaussian distribution number generator, or if you have any code snippet to pass.

Thanks in advance.

Answer 1

The standard library does not. Boost.Random does, however. I'd use that if I were you.

Answer 2

The GNU Scientific Libraries has this feature. GSL - Gaussian Distribution

Answer 3

C++ Technical Report 1 adds support for random number generation. So if you're using a relatively recent compiler (visual c++ 2008 GCC 4.3), chances are that it is available out of the box.

See here for sample usage of std::tr1::normal_distribution (and many more).
