It provides the first proof that when the operator q is linear and symmetric, AA improves the root\u002Dlinear convergence factor over the fixed\u002Dpoint iterations. When q is nonlinear, yet has a symmetric Jacobian at the solution, a slightly modified AA algorithm is proved to have an analogous root\u002Dlinear convergence factor improvement over fixed\u002Dpoint iterations. Simulations verify our observations. Furthermore, experiments with different data models demonstrate AA is significantly superior to the standard fixed\u002Dpoint methods for Tyler\u0027s M\u002Destimation.\u003C/p\u003E",
