摘要
研究矩阵C-特征值的估计问题,通过引入基本C-特征值的概念,并运用在实空间中定义超平面的构造性几何方法,给出了判定非奇异矩阵的充分条件,进而研究了新的矩阵基本C-特征值的包含区间,并给出了实用估计式.
We studied the estimations for coneigenvalues of a matrix, introduced the concept of basic coneigenvalues, and gave some sufficient conditions to identify a nonsingular matrix by means of the constructive geometry method that defines hyperplane in real spaces. Moreover, a new inclusion interval of basic matrix coneigenvalues was also studied and a useful estimation was also given.
