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;
