If this value is zero, it means AA is a zero matrix and the definition of matrix 1-norm is trivially true. If this value is not zero, by letting x=(δij0)ni≥1x=(δij0)i≥1n with δij0δij0 being the Kronecker delta, we have ∥Ax∥1∥x∥1=∑ni=1|aij0|1=max1≤j≤n...
spectral normsymmetric matricesThe paper deals with rank, trace, eigenvalues and norms of the matrix C x = ( x i x j ) i , j = 1 n , where x i are i th components of any real sequence ( x n ) . A result in this paper is that the Euclidean and spectral norms of the ...

We derive spectral estimates on the norm of the resolvent for two classes of matrices. First, we consider matrices, whose largest singular value is bounded by 1. We recover and generalize the estimates obtained by E.B. Davies and B. Simon for such matrices. In the second part we improve ...
The conditions for a matrix to have all its eigenvalues inside an ellipse are obtained and explained in terms of a vector norm. A set of functions orthogonal on the ellipse is obtained and the relation between the Chebyshev filter and these functions is presented. The Butterworth filter is deri...

In the following, it will be shown that there is an important connection between the controllability and the design of state feedback control law. In particular, if a system is controllable, it is possible to modify via feedback all the eigenvalues of the dynamics matrix A, and thus to ...
