[How can I use the eigensolvers configs in eigen_examples?] #322

Eigen Solvers I'm confused about how to convert this file into a correct json file that could be recieved by eigensover.c. "default:config_version=2 default:eig_solver=JACOBI_DAVIDSON default:eig_max_iters=128 default:eig_tolerance=1e-4 default:eig_which=largest

gmres accelerator config

default:solver(main)=FGMRES main:gmres_n_restart=10 main:preconditioner(amg)=NOSOLVER

outer solver setup

main:convergence=RELATIVE_INI main:norm=L2 main:use_scalar_norm=1 main:max_iters=20 main:tolerance=1e-2

printing obtions

main:print_solve_stats=1

main:monitor_residual=1

main:obtain_timings=1"
