Hi, is it OK to ask usage questions here?
Specifically, I want to use Ridge regression, both for over- as well as underdetermined systems.
But it seems that only one case is implemented:
https://github.com/elemental/Elemental/blob/master/src/lapack_like/euclidean_min/Ridge.cpp#L30
I wonder if I can just append zero columns to fit in the case, or whether that idea breaks down, because the rank will be too low then?
