Random number generator (GSL) More...
#include <gsl_rnga.h>
If seed
is zero, or is not given, then the default seed specific to the particular random number generator is used. No virtual functions are used in this class or its parent, rnga. This should be as fast as the original GSL version.
An interesting application of this class to generate an arbitrary distribution through a Markov chain Monte Carlo method is in Generate an arbitrary distribution.
