Structural index reduction algorithms for differential algebraic equations via fixed-point iteration
Juan Tang, Wenyuan Wu, Xiaolin Qin +1
Motivated by Pryce's structural index reduction method for differential algebraic equations (DAEs), we show the complexity of the fixed-point iteration algorithm and propose a fixe…
