However, when the permittivity of the scatter becomes large, the convergence rate of Krylov subspace iterative methods slow down. Therefore, the inner–outer flexible generalized minimum residual method (FGMRES) is used to accelerate the iteration. As a result, nearly 10 times convergence improvement...
The output is the estimated dipole moment vector for each point of the source space, and a diagnostics matrix indicating the number of inner iterations for each outer iteration, and the relative change in when tolerance is reached. 4. _ : This function plots the activity map, that is ...

In this paper, flexible inner-outer Krylov subspace methods, which are implemented using the fast multipole method (FMM) for solving large-scale electromagnetic wave problems, are presented. The flexible Krylov subspace methods refer to a class of methods that accept variable preconditioning. To ...
