Abstract:The Zu-type method for the differential-algebraic equation can satisfy the constraint equations at each time node and can be implemented easily because its easy computational format.Hence,the Zu-type method is quite practical.Herein,the Zu-type method was found to be not only constraint-preser-ving but also symplectic.
