Thank you for your great proposal.

Feature #10073: [PATCH] Implement Laplace expansion for matrix.

----------------------------------------
Laplace expansion has really important mathematical property.

We can handle many thing with this (determinant, cross product)

So I'm confident that this method is necessary.

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.
