There was a problem hiding this comment.
May be you could add that this is a helper function for methods like adjacency_matrix, kirchhoff_matrix, etc.

…x}`: Support constructing `End(CombinatorialFreeModule)` elements
<!-- ^ Please provide a concise and informative title. -->
<!-- ^ Don't put issue numbers in the title, do this in the PR
description below. -->
<!-- ^ For example, instead of "Fixes sagemath#12345" use "Introduce new method
to calculate 1 + 2". -->
<!-- v Describe your changes below in detail. -->
<!-- v Why is this change required? What problem does it solve? -->
<!-- v If this PR resolves an open issue, please link to it here. For
example, "Fixes sagemath#12345". -->
This is a follow-up after
- sagemath#37692
... to cover a few more methods. The methods can now create
endomorphisms of free modules whose bases are indexed by the vertices.
To help with this, we make the `matrix` constructor a bit more flexible.
This is also preparation for making the spectral graph theory methods
ready for `CombinatorialFreeModule`:
