Also known as weak diagonally dominant matrix
matrix in which the magnitude of the diagonal entry in a row is no less than the sum of the magnitudes of the nondiagonal entries in that row
对角占优矩阵是指一矩陣的每一橫行,對角線上元素的大小大於或等於同一橫行其他元素大小的和,一矩陣A為对角占优矩阵若 其中aij為第i行第j列的元素。 上述的定義中用到大於等於,其條件較鬆,因此有時會稱為弱对角占优矩阵,若上述的定義用大於代替大於等於,則稱為強对角占优矩阵。对角优势矩阵可以指弱对角占优矩阵,也可以指強对角占优矩阵,視上下文而定。
