Class AcceptanceRejectionRandomNumberGenerator

java.lang.Object

net.finmath.randomnumbers.AcceptanceRejectionRandomNumberGenerator

All Implemented Interfaces:

Serializable, RandomNumberGenerator

public class AcceptanceRejectionRandomNumberGenerator
extends Object
implements RandomNumberGenerator

Class implementing RandomNumberGenerator by the acceptance rejection method. Note that the acceptance rejection methods requires a two dimensional uniform random number sequence with independent components.

Method Detail

getNext

public double[] getNext()

Description copied from interface: RandomNumberGenerator

Get the next sample vector of dimension n, where n is getDimension. An implementation has to be thread safe.

Specified by:

getNext in interface RandomNumberGenerator

Returns:

The next sample vector of dimension n, where n is getDimension.

getDimension

public int getDimension()

Description copied from interface: RandomNumberGenerator

Get the sample vector dimension.

Specified by:

getDimension in interface RandomNumberGenerator

Returns:

The sample vector dimension n.
