    • jacobian

      double[][] jacobian(double t, double[] y, double[] yprime)
      Used to compute the Jacobian of the function at t.
      Parameters:
      t - a double, the point at which the function is to be evaluated. (Input)
      y - a double array which contains the dependent variable values. (Input)
      yprime - a double array which contains the value of the function \( \frac{dy}{dt} = y^{'} = f(t,y) \). (Input)
      Returns:
      a double y.length by y.length matrix containing the value of the Jacobian of the function at t. (Output)
