Thank you so much. ---------------------------------------- Feature #10072: [PATCH] Implement Vector.basis https://bugs.ruby-lang.org/issues/10072#change-49275 * Author: gogo tanaka * Status: Closed * Priority: Normal * Assignee: Marc-Andre Lafortune * Category: lib * Target version: current: 2.2.0 ---------------------------------------- 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. ---Files-------------------------------- implement_Vector.basis.patch (1.59 KB) -- https://bugs.ruby-lang.org/
