An extension of the Majorize-Minimize Memory Gradient algorithm for minimizing functions of complex variables is proposed.The convergence of the algorithm is proved under weak assumptions.A novel application of the algorithm to parallel Magnetic Resonance Imaging reconstruction is proposed.Through simulations...
Under the assumption that F satisfies the Kurdyka-Lojasiewicz property, we give conditions under which the sequence generated by the resulting block majorize-minimize subspace algorithm converges to a critical point of the objective function, and we exhibit convergence rates for its iterates....
