摘要
研究具有广泛应用背景的广义对角占优矩阵的充分条件,获得了几个简捷的实用结果。所得条件允许矩阵的非对角占优行可达n-1行,运用于广泛的矩阵类。
Generalized diagonal dominant matrices play in important role in many fields,such as matrixtheory,numerical mathematics and control theory etc.But it is difficult to determine if a matrix is a genralized matrix.In this paper,several simple practical criteroa of generalized diagonal non -predominantmatrices are obtained,and the results permite the numbers i of rows,which diagonal entries are notdominant,satisfies 1≤i≤n-1。
