Does anybody know of an implementation of the Moore–Penrose

different name, I ask here.
I looked once but didn't find anything. We're missing the SVD for rings
like RR, or it would be easy to fix.
I want the pseudo-inverse over any base field. There is no reason to
restrict to RR. The SVD on the other hand is not defined over any field.
Anyway, I need the pseudo-inverse, so I'll have to implement it myself.
