Description

This package includes functions for stability analysis of square numerical matrices and polynomials with numerical coefficients. Specifically, the number of roots z satisfying the inequality Re[z] < bound (or Abs[z] < bound) can be computed avoiding the explicit finding of roots; number bound is supplied by the user.
