Class Method Details

.new([seed]) ⇒ Object

Generate an instance of Numo::GSL::Rng::Random32Glibc2 class, a subclass of Numo::GSL::Rng class with gsl_rng_random32_glibc2 type.

This function returns a pointer to a newly-created instance of a random number generator of type T. For example, the following code creates an instance of the Tausworthe generator,

gsl_rng * r = gsl_rng_alloc (gsl_rng_taus);

If there is insufficient memory to create the generator then the function returns a null pointer and the error handler is invoked with an error code of GSL_ENOMEM.

The generator is automatically initialized with the default seed, gsl_rng_default_seed. This is zero by default but can be changed either directly or by using the environment variable GSL_RNG_SEED (Random number environment variables).

The details of the available generator types are described later in this chapter.

Parameters:

  • seed (Integer) —

    Random seed.
