chebycenter(A,b,r0)

Computes the Chebyshev center and Chebyshev radius of a polytope.

This function returns the Chebyshev center and Chebyshev radius of a polytope defined by linear inequalities Ax<=b. The Chebyshev center of a polytope is the center of the largest hypersphere enclosed by the polytope. Similarly the Chebyshev radius is the radius of the largest hypersphere enclosed by the polytope.
