The paper deals with the numerical calculation of the numerical radius of a complex matrix. The derived methods consist mainly of matrix-vector multiplications, being based on the power method for calculating the largest eigenvalue (in modulus) of a Hermitian matrix. Computational tests are given to show the efficiency of the proposed algorithm.
