[Trilinos-Users] compute eigenvalues of an ill-conditioned matrix

[Da Zheng]

Hello,

I'm trying to use the Anasazi eigensolvers to compute spectral
embedding of a very large graph (|V| ~ 4 billion and |E| ~ 129
billion). I'm just curious if the eigensolvers such as Krylov Schur
can compute eigenvalues with a high precision even if the sparse
matrix has a very high condition number?

Thanks,
Da
