You should probably define those terms in the documentation.

That does not strike me as quite the same.

Good. But It still needs to be testet if the performance equals that
of normal arrays or matrices of floats.

It seems like a good start.

I can only say, that if the runtime performance cost is zero, then
I would find the library very interesting, and I would not hessitate
to use it in my work on Bayesian Networks.
