Inequalities

NOREDUND - Remove redundant linear inequalities from a set of inequalities; i.e., remove redundant linear constraints defining a feasible region. Note that the feasible region satisfies A*x

CON2VERT - convert a convex set of constraint inequalities into the set of vertices at the intersections of those inequalities;i.e., solve the "vertex enumeration" problem.V = con2vert(A,b)Converts the polytope (convex polygon, polyhedron, etc.) defined by the system of inequalities A*x = n (m...

Determinantal matrix representations of hyperbolic polynomials are a current topic of interest and research among those working with LMI's (Linear Matrix Inequalities) and SDP (semi-definite programming). This toolbox was used to demonstrate some of the theorems presented in the author's Ph.D....
