Detailed Description

Class implements Mersenne Twister RNG.

Class implements Mersenne Twister algorithm (known as MT19937). See [30]

Remarks

Class uses algorithms implemented in GSL

Constructor & Destructor Documentation

julian::MersenneTwister::MersenneTwister

(

)

Constructor.

in constructor we create the GSL MersenneTwister algorithm

julian::MersenneTwister::MersenneTwister

(

const MersenneTwister &

orig

)

Copy constructor.

One need to explicitly define copy constructor to avoid memory-leak.

julian::MersenneTwister::~MersenneTwister ( )

virtual

destructor

One need to explicitly define destructor to avoid memory-leak.

Member Function Documentation

MersenneTwister * julian::MersenneTwister::clone ( ) const

virtual

Virtual copy constructor.

Method is an implementation of virtual copy constructor.

Reimplemented from julian::UniformRNG.

double julian::MersenneTwister::getRandom ( )

virtual

generate one random variable from uniform distribution.

Implements julian::UniformRNG.

std::vector< double > julian::MersenneTwister::getRandoms ( int  n )

virtual

generate n random variables from uniform distribution.

Implements julian::UniformRNG.

MersenneTwister & julian::MersenneTwister::operator=

(

MersenneTwister

orig

)

Copy assignment operator.

One need to explicitly define Copy constructor to avoid memory-leak.

void julian::MersenneTwister::setSeed ( unsigned int  seed )

virtual

sets seed of RNG

Implements julian::UniformRNG.
