Matrix calculus [2], [7] is used to derive formulas for the derivatives of the coefficients of the characteristic polynomial with respect to any matrix of physical parameters. Two of these derivatives ...

In this paper, we propose new criterion for realizability of characteristic transfer-function matrices, which are the transfer-function matrices with the characteristic polynomial as their common ...
