Hi,
This is more of a feature request than an actual issue, but I was wondering if it is possible to combine the CPR solvers with the block-solvers. Say that I have a block system where the entries…

Hi Jutho!
I'm not sure if this is a bug, but I noticed that eigsolve() does not always return normalized eigenvectors. Are the eigenvalues supposed to be normalized? I couldn't see anything about t…

This would be co…

I _might_ be using the library incorrectly, but if not, then I may have found a limitation in the Schur decomposition algorithm on a 2x2 matrix. The decomposition as done in the following code leads t…

I'm getting a segmentation fault when computing the schur decomposition of a 0-dimensional matrix. That is supposed to fail, but it should not crash. I'm only getting this error if I import `rpy2` (py…

This is an unintuitive behavior for me given the way that `eigs` used to work.

julia> A = randn(100,21); A = A*A';
julia> schur_to_eigen(partial_schur(A, nev=8, which=LM())[1])[1]

In this line I think the type constraint to too tight. We only need some `size` and `eltype`
