In summary, a large-scale eigen solver package for Fortran is a software tool specifically designed to solve systems of linear equations for a large number of variables using the Fortran programming language. It uses advanced numerical methods and algorithms to efficiently handle large matrices and find eigenvalues and eigenvectors. The benefits of using such a package include improved efficiency and accuracy in solving complex systems, faster computation time, and applicability to a wide range of matrices. There are also open-source options available, including LAPACK, ARPACK, and SLEPc, that are continuously developed and improved by the scientific community.

Dear All,


I would like to know what type of solver packages can be used for solving the Large scale eigen problems, implemented in the Fortran language. Especially the simultaneous, subspace, ritz vectors, Lanczos etc.. methods is a must in the package. Does any of you aware of such packages ?

Your entry point will be appreciated?
