【Abstract】 Based on the existed numerical methods of ordinary differential equations,a class of extended Rosenbrock numerical simulation methods for solving neutral discrete-distributed delay systems were constructed by using skills like matching appropriate compound quadrature formulas to discretize the distributed terms.For linear test systems,the asymptotically stability of new methods were investigated and some criteria were derived.Numerical experiments illustrated the computational effectiveness of the obtained methods and the stability results.更多还原
