View on Github →feat(linear_algebra/affine_space): affine combinations for finsets (#3122)
Extend the definitions of affine combinations over a `fintype`

to the
case of sums over a `finset`

of an arbitrary index type (which is
appropriate for use cases such as affine independence of a possibly
infinite family of points).
Also change to have only bundled versions of `weighted_vsub_of_point`

and `weighted_vsub`

, following review, so avoiding duplicating parts
of `linear_map`

API.
