I'm trying to play with some algorithms in the graph embedding literature (e.g. locality preserving projections) which need to solve the generalized eigenvalue. The Matlab 'eigs' function has this opt…

Can you extend the code to solve Generalized eigenvalue problems
L\nu = \lambda W \nu
Currently, if I have to solve this, then, I would have to convert this to a standard eigenvalue problem, like,
…

@JoseMath and @ltrbuse are interested in having a method to find generalized eigen- values/vectors.
Either wait until `eigen` can be used in M2 or wrap `lapack` routines:

Does this code support also the [generalized eigenvalue problem](https://en.wikipedia.org/wiki/Eigendecomposition_of_a_matrix#Generalized_eigenvalue_problem) given a pair of matrices (A,B)? (what [LO…

As far as I could tell, there is no way in mpmath to solve the generalized eigenvalue problem `Ax = lambda Mx`. Is there any hope of adding this functionality?

Hello,
I was trying to find an appropriate example for solving the following generalized eigenvalue problem:
Ku = xMu, where K is the stiffness matrix, M is the mass matrix and u is the eigenvecto…

Timon @TSGut has done the heavy lifting and has implemented Jacobi matrices for Zernike polynomials on a disc.
Alberto @APaganini could you remind us what exactly you required? If I remember corre…

Hi,
I am having trouble computing eigenvalues with arpack for the following eigenvalue problem:
```
M1 x = lambda M0 x
```
The matrices M1 and M0 are 178x178 and are attached wit…

I'm trying to solve a generalized eigenvalue problem but I have no idea what functions in this toolbox I should use. Are there any eigenvalue solvers in this toolbox? I really appreciate it if you cou…

### Details
It seems that `scc` array is allocated, maintained but not accessed by actual `diag_zhegvx` procedure of reduced basis set.
In `diago_david.cpp`,
`scc` is updated and referenced her…
