Abstract
We make an experimental comparison of methods for computing the numerical radius of an 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 real variables. We make comparisons with respect to both accuracy and computation time using publicly available software.
