Hi, MFEM developers,
We are looking for test cases of generalized eigenvalue problem for our eigensolver package, EVSL. I came across example 12 in mfem that is Linear Elasticity Eigenproblem. Mfem…

Given a square matrix `M` over a field and an element `t` of the field, it is easy to compute the dimension of the left eigenspace of `M` with eigenvalue `t`, by computing the rank of `M-t` and subt…

Hi,
Thanks for the fastest tool for EIGEN implementation, it's so useful for very large matrices. I am working with a FE project which is related to solving eigenvalues of a system.
I am getting d…

The `eigs` and `svds` implementation needs the following features to be completed:
- [ ] Support for the generalized eigenvalue problem
- [ ] Implement shifts (We now have dense and sparse direct solv…

I've finished setting up LanDosG such that it can now handle the standard eigenvalue problem in addition to the generalized eigenvalue problem (and updated the TESTS/Landos/LanDos.c test to show the n…

When I use the single & double precision complex ARPACK routines using the generalized approach, for the non-shift-invert version the problem does not converge, and for the shift-invert problem the ei…
