Detailed Description

Generates numbers from a histogram in a continuous manner.

Constructor & Destructor Documentation

theplu::yat::random::ContinuousGeneral::ContinuousGeneral ( const statistics::Histogram hist  )  [explicit]

Constructor.

Parameters:
hist is a Histogram defining the probability distribution


Member Function Documentation

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.

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).

unsigned long theplu::yat::random::Continuous::seed_from_devurandom ( void   )  [inline, inherited]

Set the seed using the /dev/urandom device.

Returns:
The seed acquired from /dev/urandom.
