Extreme eigenvalue problem

Hello,

I read this article on a FEAST add-on that automatically estimates an eigenvalue search interval and a subspace size when the user is only interested in the lowest or highest k eigenvalues of a standard or generalized eigenvalue problem:

Could I please get a copy of the package for a Windows / Fortran interface? Thank you very much for the support.
