Detailed Description

Generates numbers from a histogram in a continuous manner.

Member Typedef Documentation

result_type

typedef double theplu::yat::random::Continuous::result_type

inherited

type returned by operator()

Since

New in yat 0.10

Constructor & Destructor Documentation

ContinuousGeneral()

theplu::yat::random::ContinuousGeneral::ContinuousGeneral ( const statistics::Histogram &  hist )

explicit

Constructor.

Parameters

hist	is a Histogram defining the probability distribution

Member Function Documentation

operator()()

double theplu::yat::random::ContinuousGeneral::operator() ( void  ) const

virtual

The number is generated in a two step process. First the bin in the histogram is randomly selected (see DiscreteGeneral). Then a number is generated uniformly from the interval defined by the bin.

Returns

A random number.

Implements theplu::yat::random::Continuous.

seed()

void theplu::yat::random::Continuous::seed ( unsigned long  s ) const

inherited

Set the seed to s.

Set the seed to s in the underlying rng. If s is zero, a default value from the rng's original implementation is used (cf. GSL documentation).

Deprecated:

Provided for backward compatibility with the 0.7 API. Use RNG::instance()->seed(s) instead.

seed_from_devurandom()

unsigned long theplu::yat::random::Continuous::seed_from_devurandom ( void  )

inherited

Set the seed using the /dev/urandom device.

Returns

The seed acquired from /dev/urandom.

Deprecated:

Provided for backward compatibility with the 0.7 API. Use RNG::instance()->seed_from_devurandom() instead.
