New gmres #65

Closed RerRayne closed 6 years ago

daskol commented 6 years ago

What is an issue for the rewriting of GMRES()?

RerRayne commented 6 years ago

Looping issues. Sometimes we get delta=1e-6/1e-7, after that AMEN crashes in matvec or a whole algorithm gets stuck in an infinite loop.

daskol commented 6 years ago

Could you provide an example of problem when GMRES() stucks? It could be good test.
