A note on positive deniteness and stability of interval matrices
Hana Veiseh · Theory of Approximation and Applications · 2013
It is proved that by using bounds of eigenvalues of an interval matrix, some conditions for checking positive definiteness and stability of interval matrices can be presented. These conditions have been proved previously with various methods and now we provide some new proofs for them with a unity method. Furthermore we introduce a new necessary and sufficient condition for checking stability of interval matrices.
