I am trying to solve a generalized eigenvalue problem with the following codes:
```julia
@var sigma u[1:2]
A = [1 2;3 4]
B = [0 1;3 2]
f = System([(sigma*A-B)*u;],

Good morning,
sorry to bother, but I have a question about a possible feature implemented in PySCF.
Does PySCF have an implementation of the Davidson diagonalization algorithm for generalized eige…
