VerifyRealRoots is a MATLAB package for computing real verified solutions of polynomial systems of equations and inequalities. Two algorithms are provided for verifying the existence of real solutions of polynomial systems. The first one is based on the critical point method and the homotopy continuation method, and the second one is based on the low-rank moment matrix completion method.
