## Abstract We consider Hamiltonian matrices obtained by means of symmetric and positive definite matrices and analyse some perturbations that maintain the eigenvalues on the imaginary axis of the complex plane. To obtain this result we prove for such matrices the existence of a diagonal form or, a
Real positive definite Hankel matrices H n have spectral condition numbers which are exponentially increasing with n. This paper attempts to characterize those matrices ฤคn in this class which are minimally conditioned, and to describe some of their properties. We also compute ฤคn explicitly for n 16.
