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));

Syntax

state = initialStateWithXorshift64star(localSeed, globalSeed, nState)

Inputs (3)

Outputs (1)

state

Type: Integer[nState]

Description: The generated initial states
