An experimental comparison of methods for computing the numerical radius
We make an experimental comparison of methods for computing the numerical radius of an n×n complex matrix, based on two well-known characterizations, the first a nonconvex optimization problem in one real variable and the second a convex optimization problem in n2+1 real variables. We make compariso...
