  • Abstract
    The sensitivity, of a characteristic root of an n by n real matrix is measured by the Euclidean norm of the root\´s n2derivatives with respect to the elements of the matrix. Let λ denote a real root and \\sigma + j\\omega a complex root. Conditions for minimizing the sensitivity norms based on \\lambda , \\sigma , \\omega , and |\\sigma + j\\omega | are obtained. Since the conditions apply for all n and involve simple algebraic properties of the matrix, they may have useful applications.
