Hi
Can I use Hypre in Eigen?

I don't known Hypre but if it can accept sparse matrices in the standard compressed column/row storage format, then you can probably easily write a wrapper. See the outerIndexPtr(), innerIndexPtr(), and valuePtr() method of the SparseMatrix class to access to is internal storage to be passed to Hypre.

Thanks, the "Hypre" is from http://acts.nersc.gov/hypre/. It is a library for solving large, sparse linear systems of equations on massively parallel computers.

Hope eigen can support it.
