I'm working to solve the multigroup neutron diffusion equations.
It is essentially a coupled system of diffusion equations that represents an eigenvalue problem for eigenvalue and…

Study and consider implementing this approach:

There might be something to do about the interpretation of the resulting vectors in te…

ex09 is running differently to how I remember. I remember the second solve with `solver_iter_pcg`, using `M=build_pc_ilu(Aint), as being faster than the first, with `M=None`. (That was presumably th…

Hello, everyone,
I have a problem with the frequency calculated.
when I use ansys calculated I can get `[2871,6168,8689,11468]`
When I try to get the mass and stiffness matrix from a .full file w…

I'm considering rewriting some of the routines in python-control so that it will no longer depend on SLICOT. The main reasons for this are that 1) because S…

See discussion in #1012.
@lbalicki, as I understand https://www.netlib.org/lapack/lug/node89.html, then every EV smaller than the largest eigenvalue times machine precision should be considered as …

I started testing your latest code from the 1.y.z branch and found a problem. I'm solving a generalized problem using shift-invert and buckling mode with shift 1.0. While ARPACK gives the correct resu…

Could you please give an example about it in Eigen or Armadillo format? It's hard for me to understand how to add shifts_f and access eigenvalues. Thanks a lot.

Hi, @FilippoMB @danielegrattarola , I have several questions w.r.t Equation (6).
1. what's the definition of ![image](https://user-images.githubusercontent.com/7151215/101278091-062b9700-37f4-11eb-…
