摘要
指出了使用Sylvester结式和Bezoutian阵的一次试验法的不足,提出了判定区间多项式根分布不变性的充要条件,它只需其中四个多项式的根分布,便可检验整个区间多项式的根分布.
The shortage of the 'one shot test'approach using sylvesters resultant matrices and Bezoutian matrices is pointed out,and the sufficient and necessary conditions for checking the invariance of root distribution of interval polynomial is suggested.This approach only requires the root locations of four polynomials to check the root distribution of an inteval polynomial.
