矩阵函数零空间中的连续正交基及其应用

Continuous Orthonormal Basis in the Null Spaces of Matrix Functions

从实际问题中引出了矩阵函数零空间中正交基的问题，讨论了其连续性和光滑性，给出了便于实施的求法．并将结果用于多体力学微分代数方程组，解决了将其化为普通微分方程组的一个难点．

In this paper,the continuity and smoothness of orthonormal basis in the null space of matrix functions and its applications in dynamics are discussed.An algorithm of it is given.
