Based on quadrature using spherical designs, we investigate Newton’s method as well as a fixed point scheme. These methods serve as alternatives to the original approach utilizing elliptic integrals. We compare the convergence behavior and the computational performance of both algorithms. 4950 https://doi.org/10.1002/pamm.202400202$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:hbz:465-20250224-150413-6$xR$3Volltext$534 4961 https://duepublico2.uni-due.de/receive/duepublico_mods_00083133 5051 620
