Detailed Description

Routines for generating series of pseudo-random or quasi-random numbers.

LIBBN support for pseudo-random number generation.

Typedef Documentation

bn_numgen

typedef struct bn_num_s* bn_numgen

The following container holds all state associated with a particular number generator. The details of that state are specific to the type of selected generator and are not public, but the container allows libbn to avoid using globals to maintain state - instead, each "generator" instance has its own state.

Function Documentation

bn_sph_pnts()

void bn_sph_pnts	(	point_t *	pnts,
		size_t	cnt,
		bn_numgen	n
	)

Generate points on a unit sphere per Marsaglia (1972): https://projecteuclid.org/euclid.aoms/1177692644.

The user is responsible for selecting the numerical generator used to supply pseudo or quasi-random numbers to bg_sph_sample - different types of inputs may be needed depending on the application.
