Remarks

Use the CvodeIntegrator class to integrate any system of ordinary differential equations using an adaptive algorithm that works on well-behaved and stiff systems.

The system of differential equations is defined using a DifferentialFunction delegate. This is a delegate that takes one real argument (the time value), and two vector arguments (the current value and the current derivative). The last argument is passed by reference and must also be returned.

To set up an integration, set the DifferentialFunction property equal to the object that defines the system. Set the InitialTime and InitialValue properties to the initial time value and function values, respectively.

To perform the actual integration, call the Integrate(Double) method with the desired final time. This method returns the function value at the final time. You can call this method multiple times to get function values at intermediate positions.
