Information

Syntax

state = Xorshift128plus.initialState(localSeed, globalSeed);

Description

Generates an initial state vector for the Xorshift128plus random number generator (= xorshift128+ algorithm), from two Integer numbers given as input (arguments localSeed, globalSeed). Any Integer numbers can be given (including zero or negative number). The function returns a reasonable initial state vector with the following strategy:

The Xorshift64star random number generator is used to fill the internal state vector with 64 bit random numbers.

Example

  parameter Integer localSeed;
  parameter Integer globalSeed;
  Integer state[Xorshift128plus.nState];
initial equation
  state = initialState(localSeed, globalSeed);

Interface

function initialState
  extends Interfaces.initialState(final stateSize = Xorshift128plus.nState);
end initialState;
