Is there a way to use clojures `rational` number for elements within a matrix? #92

Hi, I know this might sound like an odd question but I have to use an algorithm for matrices that are not very large. Therefore, performance is not an issue, what is an issue is the loss of accuracy.

This is why I am wondering if I could use clojure's rational number system (rationalize) when creating a matrix like

(dge rationalize  2 2 [ 1 2 3 4])

Regards.

I am not sure that I understand what rationalize would do exactly.

If you're asking whether it would be possible to have a Neanderthal backend that would perform computations using Clojure's rational numbers, that is possible. Someone would have to implement that backend. And it would be slow.
