是这个意思，Ds是一个由0或者1组成的m×m对角矩阵。就是矩阵里的项不是0就是1
dia_matrix,全称Sparse matrix with DIAgonal storage,是一种对角线的存储方式。如下图中,将稀疏矩阵使用offsets和data两个矩阵来表示。offsets表示data中每一行数据在原始稀疏矩阵中的对角线位置k(k>0, 对角线往右上角移动;k<0, 对角线往左下方移动;k=0,主对角线)。该格式的稀疏矩阵可用于算术运算:它们...
a diagonally dominant symmetric matrix with all nonnegative diagonal elements Proof Assume that \exists \lambda<0 A {\rm \ is \ diagonally \ dominant \ }\Rightarrow |a_{ii}|\geq\mathop{\sum}\limits_{j=1,\ldots,n,j\neq i}|a_{ij}|,\quad i=1,\ldots,n Gershgorin Circle Theor...
For matrix , with off–diagonal elements not necessarily of the same sign, conditions are obtained for the existence of a positive definite diagonal matrix , such that matrix + is positive definite; and the applications of the latter to the determination of the stability of interval matrices are...

We obtain a necessary and sufficient condition for a given complex matrix A to be stochastically similar to a matrix with any diagonal elements the sum of which equals trace A . Then an inverse elementary divisor result for quasistochastic matrices is obtained. 关键词: UNCERTAIN SYSTEMS ROBUST ...
The simplest pattern matrix is the diagonal matrix D, defined as a square n × n matrix with all off-diagonal elements being equal to zero, i.e. dij = 0, if i≠ j. The diagonal in this case is referred to as the principal diagonal. If the diagonal elements are unitary, we have ...
