### computeParameterJacobian

    void computeParameterJacobian(double t,
                                  double[] y,
                                  double[] yDot,
                                  java.lang.String paramName,
                                  double[] dFdP)
                                  throws DimensionMismatchException,
                                         MaxCountExceededException,
                                         UnknownParameterException

  Compute the Jacobian matrix of ODE with respect to one parameter.

  If the parameter does not belong to the collection returned by `Parameterizable.getParametersNames()`, the Jacobian will be set to 0, but no errors will be triggered.

  Parameters:
    `t` - current value of the independent time variable
    `y` - array containing the current value of the main state vector
    `yDot` - array containing the current value of the time derivative of the main state vector
    `paramName` - name of the parameter to consider
    `dFdP` - placeholder array where to put the Jacobian matrix of the ODE with respect to the parameter
  Throws:
    `MaxCountExceededException` - if the number of functions evaluations is exceeded
    `DimensionMismatchException` - if arrays dimensions do not match equations settings
    `UnknownParameterException` - if the parameter is not supported
