When requested about extending N to an arbitrary amount, the at the rear of-routine-professor did some handwaving about matrix math.

Large sparse matrices normally crop up when undertaking numerical calculations. Commonly, our knowledge isn’t sparse although the ensuing information constructions we generate may very well be sparse. There are a selection of strategies/procedures utilized to retail outlet sparse matrices. Methods for producing sparse matrices can be found from the Matrix package19.
Summing up the absolute values is often especially challenging. E.g., say you desired your “invested portfolio sizing†to become a lot less than some sum.
