Hi,
I think it could be great to introduce the support for eigenvalue solvers. I noticed that the implicit restarted method has already been passed. The modern faster method should be the Krylov-Sc…

Note: many integrators for linear systems also use exponential-like matrix functions and Krylov approximations (Magnus expansion, adiabatic integrators, symplectic exponential methods, etc). Since the…

Hi and thanks for this package! I'm interested in matrix-free problems (matvecs provided as a function), are any of the solvers usable?

### 🚀 The feature, motivation, and pitch
I want to contribute to the PyTorch community with my implementation of CG and BICGSTAB methods; I believe this will immensely help research students who wo…

Some rotor models can have a large number of elements and, in addition to this fact, the high number of frequency / time sample points that may be necessary to input, may lead to a very long time and …

The Problem
-----------------
After already reviewing a couple of other implementations of Krylov solvers, today I looked into the TFQMR pull request (#23). After taking a closer look, I realized …

This issue collects the ideas that go into the roadmap for Expmv.jl. The basic problem is to calculate `v = kappa(dt*A)*u)`, where `kappa(z)` is some approximation to `exp(z)`. This should be done in-…

The idea is to implement internal convergence checks (based on e.g.
extrapolation technique) to make the code fully adaptive. So it may
automatically converge to the desired accuracy using minimum…

Taking a closer look at how the Krylov evolution works, I noticed that it may be computationally inefficient. A small study of this is done in the script below [1], which executes nonequilibrium dynam…
