隨機數發生器

本庫提供了一批隨機數發生器，它們可由一個通用接口訪問。可以通過環境變量實時的選擇不同的隨機數發生器和隨機數種子，以便在不同的生成器間切換，而不必重新編譯。 Each instance of a generator keeps track of its own state, allowing the generators to be used in multi-threaded programs. Additional functions are available for transforming uniform random numbers into samples from continuous or discrete probability distributions such as the Gaussian, log-normal or Poisson distributions.

這些函數在頭文件 gsl_rng.h 中聲明。
