I see that it is a special case of the elliptical distribution (which sounds like it should be called the ellipsoidal distribution). Should we have the more general case as well?
Sure... it should be "easy" -- just pass in a vector holding the lengths of the major axes. Should be easy to implement, too. ... I leave this to Arvydas?
Is that OK with you, Arvydas?
On a related note: Is there a srfi for matrix math?
There isn't. Unless you need it right away, I would hold off until we know whether SRFI 164 or SRFI 179 becomes the R7RS-large multidimensional array SRFI. However, it should be possible to support either on top of the other one.

my theory." Latin students think "'Probat' means 'tests': the exception puts
the rule to the proof." But legal historians know it means "Evidence for an
exception is evidence of the existence of a rule in cases not excepted from."
