Subject: [ruby-core:65403] [ruby-trunk - Feature #10072] [PATCH] Implement	Vector.basis

Issue #10072 has been updated by Marc-Andre Lafortune.


Interesting idea, but it has issues, like private new currently requiring an array, and it being two steps, the first one not too clear.

I think it's best to pick between the two possibilities I gave.

----------------------------------------
Standard basis vectors are really important in linear algebra.

And we usually need this when we use matrix or vector. (base conversion, principal component analysis...

This is why I implemented.

But I recognize Ruby should be not for mathematician but rubyist.

Ruby doesn't need too academic method.

So If you think it is too academic you can ignore my patches.


gogo.
