## I'm using arpack on visual studio 2015 + intel fortran 2017 to solve generalized eigenvalue of finite element method.
**I found that if nev is too small, the eigenvalue is completely error, like f…

Hi,
Does anyone know if there is a member function under DenseMatrix that can solve generalized eigenvalue problem, i.e. Av=\lambda Sv where A and S are of class DenseMatrix and they are symmetric po…

As we have observed several times e.g. #1, julias `eigs` is broken for a large class of generalized eigenvalue problems. As pointed out here https://github.com/JuliaLang/julia/issues/ 24668 this seems…

### Description of the enhancement or error report
A new capability needs to be added to MOOSE to allow for the creation/filling of multiple Matrices/Vectors. This will be accomplished by declaring …

Hi Yihuan !
I'm interested in solving a generalized eigenvalue problem for Finite Element Method.
If the solver works well on small systems, it fails to extract the eigenvalues on a large sparse s…

Currently OpenPnP uses the fiducial data to calculate a board corner offset and rotation. When a board is not perfectly scaled from the manufacturer this can result in offset errors where the work is …

I encountered a strange issue when solving the generalized eigenvalue problem in Julia 0.6 (version on mac os, but also on 0.5 and 0.6 in Juliabox). When trying to solve the generalized eigenvalue pro…

MSVC constexpr complie errors coming from std::abs for std::complex, which is used in generalized eigen solver. Even if those errors are mitigated, some constants in implementation are not suitable fo…

Multiple users reported that the eigensolvers available in Kratos are very slow when multiple eigenvalues are required (behaviour looks quadratic and is one order of magnitude slower than Siemens NX f…
