Subject: [ruby-core:65378] [ruby-trunk - Feature #10072] [PATCH] Implement	Vector.basis

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


Looks good, but I'm wondering if we should use named arguments as it's really difficult to remember the order without looking it up.

    Vector.basis(3, 0)
    # or
    Vector.basis(size: 3, index: 0)

Not sure.

----------------------------------------
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.
