摘要 首先讨论了Hessenberg index-2型微分代数方程的数值解,这类微分代数方程的数值解通过MATLAB的代数求解系统可以拓展到任意阶;然后对给定的Hessenberg系统,通过用级数的数值计算方法得到合理的逼近. Numerical solutions of differential-algebraic equations （DAEs） with Hessenberg index-2 are studied. The solution of a differential-algebraic equation can be expanded up to arbitrary order using MATLAB computer algebra systems. We calculate the power series of the given Hessenberg system, which give an appropriate approximant for solving differential-algebraic equations numerically.
