Syntax

state = Utilities.initialStateWithXorshift6star(localSeed, globalSeed, nState);

Description

The Xorshift64star random number generator is used to fill a state vector of length nState (nState ≥ 1) with random numbers and return this vector. Arguments localSeed and globalSeed are any Integer numbers (including zero or negative number) that characterize the initial state. If the same localSeed, globalSeed, nState is given, the same state vector is returned.

Example

  parameter Integer localSeed;
  parameter Integer globalSeed;
  Integer state[33];
initial equation
  state = Utilities.initialStateWithXorshift64star(localSeed, globalSeed, size(state,1));

state = initialStateWithXorshift64star(localSeed, globalSeed, nState)

localSeed	Type: Integer Description: The local seed to be used for generating initial states
globalSeed	Type: Integer Description: The global seed to be combined with the local seed
nState	Type: Integer Description: The dimension of the state vector (>= 1)

state	Type: Integer[nState] Description: The generated initial states
