Constructor & Destructor Documentation

ebl::random::random

(

int

x

)

Constructs a random number generator with seed 'x'. Use x == 0 to construct a fixed-seed generator.

ebl::random::random	(	int	argc = 0,
		char **	argv = NULL
	)

Constructs a random number generator with a random seed taken from current time and the sum of all arguments characters, if present. This can be useful if several programs are called at the same time with different input arguments.

Member Function Documentation

double ebl::random::drand

(

void

)

random number generator. Return a random number drawn from a uniform distribution over [0,1].

double ebl::random::drand

(

double

v

)

random number generator. Return a random number drawn from a uniform distribution over [-v,+v].

double ebl::random::drand	(	double	v0,
		double	v1
	)

random number generator. Return a random number drawn from a uniform distribution over [v0,v1].

void ebl::random::dseed

(

int

x

)

[protected]

sets the seed of the random number generator. This MUST be called at least once before the random number generator is used. Otherwise calls to drand() and dgauss() always return the same number.
