摘要
给出一个利用低阶矩阵的亚正定性来判断高阶矩阵的亚正定性的充分必要条件 ,其次从多个方面得出亚正定矩阵的若干判定准则 .
The necessary and sufficient condition which determinate positive subdefinity of higher order matrices by positive subdefinity of lower order matrices is obtained.Different determinate criterions for the positive subdefinite matrices are also obtained from different conditions.
