Is it written in C, or in pure Ruby? How does it work with C data structures?

What do you mean by "compress," exactly?

Most likely this is because `NMatrix#det` is not equal to `NMatrix#det_exact`. In other words, the approximation being used to compute the determinant is returning a nonzero value, and so it's...

That's not what I'm getting: ``` [1] pry(main)> NMatrix.new(3,[1.0,2,3,4,5,6,7,8,9]).det_exact => 0.0 [2] pry(main)> NMatrix.new(3,[1.0,2,3,4,5,6,7,8,9]).det => 6.661338147750939e-16 ``` You probably need to make sure you're using `dtype: :float64`. By passing 1...

Okay. I like this strategy. Go for it.

I'm actually not sure about this one. This is a particularly common problem with matrix decompositions. Usually it's solved by adding to the diagonal until the matrix is no longer...

I'd much rather we have an exposed `#inverse_exact` method which relies on `#det_exact`. How about that?

No, partial read and write are not supported. But I'm not sure a use-case supports this. When you say "is it enough," do you mean for the code contribution requirement,...

I think that'd be awesome.

Yes. I think any non-trivial contribution — to show you understand the codebase and how open source development works — is sufficient. With that said, we look very kindly on...
