Method Detail

### getParametersDimension

    int getParametersDimension()

  Deprecated.
  Get the number of parameters.

  Returns:
    number of parameters

### computeJacobians

    void computeJacobians(double t,
                          double[] y,
                          double[] yDot,
                          double[][] dFdY,
                          double[][] dFdP)
                          throws DerivativeException

  Deprecated.
  Compute the partial derivatives of ODE with respect to state.

  Parameters:
    `t` - current value of the independent time variable
    `y` - array containing the current value of the state vector
    `yDot` - array containing the current value of the time derivative of the state vector
    `dFdY` - placeholder array where to put the jacobian of the ODE with respect to the state vector
    `dFdP` - placeholder array where to put the jacobian of the ODE with respect to the parameters
  Throws:
    `DerivativeException` - this exception is propagated to the caller if the underlying user function triggers one
