I got this message regarding a survey done about Linear Algebra Software and to my surprise eigen is not there, and should be. Maybe one of the official maintainers wants to fill the survey?

Subject: LA Software Survey of Freely Available Software to be Updated
We are planning to update the survey of freely available software for
the solution of linear algebra problems. The current version of the
survey can be found at:
http://bit.ly/la-sw-survey-2021
The aim is to put in "one place" the source code that is freely
available for solving problems in numerical linear algebra,
specifically dense, sparse direct and iterative systems and sparse
iterative eigenvalue problems. Please send Dalal Sukkari
sukkari@xxxxxxxxxxx updates and corrections. We will post a note on
the na-digest when the new list is available.
Thanks,
Jack Dongarra and Dalal Sukkari
