digraph matrix realization singular value
2007/12/11
A complex matrix A is said to be a matrix realization of the digraph D if D is the associated digraph of A, and A is said to have the property B if every singular value of A is contained in the union ...
Some Simple Estimates for the Singular Values of Matrices
Singular value estimates -matrix
2007/12/11
We first provide a simple estimate for ||A~(-1)||_∞ and ||A~(-1)||_1 of a strictly diagonally dominant matrix A. On the Basis of the result, we obtain an estimate for the smallest singular value of A....
