Information

Syntax

(r, stateOut) = Xorshift64star.random(stateIn);

Description

Returns a uniform random number r in the range 0 < r ≤ 1 with the xorshift64* algorithm. Input argument stateIn is the state vector of the previous call. Output argument stateOut is the updated state vector. If the function is called with identical stateIn vectors, exactly the same random number r is returned.

Example

  parameter Integer localSeed;
  parameter Integer globalSeed;
  Real r;
  Integer state[Xorshift64star.nState];
initial equation
  state = initialState(localSeed, globalSeed);
equation
  when sample(0,0.1) then
    (r, state) = random(pre(state));
  end when;

Interface

pure function random
  extends Modelica.Icons.Function;
  input Integer stateIn[nState] "The internal states for the random number generator";
  output Real result "A random number with a uniform distribution on the interval (0,1]";
  output Integer stateOut[nState] "The new internal states of the random number generator";
end random;
