[Trilinos-Users] Large Generalized Symmetric Complex Eigenvalue Problem: From ARPACK to Anasazi?

[Klaus Zimmermann]

Hi,

as Jed pointed out to me, the 5% is completely off. Actually all the 
numbers I gave you are a bit off.
It's more like 1e7 with 0.03%-0.05% non-zero elements.
Sorry for the confusion.

Thanks, Jed, for spotting it.
Klaus
