Missing eigenvalues #90
Comments
Hi ttx, |
Did you manage to find the other eigenvalues with the higher tolerances? Can I close this issue? |
I have the some big sparse matrix to be diagonalized. When compared with the Arpack results, it seems that there are multiple eigenvalues missing in the degenerate subspace using Krylovkit.
The only change I make in my code is changing from
to
The second one use Arpack method, and here are the eigenvalues it obtained (the first 15 of it)
The first one use KrylovKit method, and here are the eigenvalues it obtained (the first 15 of it)
It seems that Krylovkit missed 2 of the 6 eigenvalues at 3.212527.
