Issue #10072 has been updated by gogo tanaka. ``` We can build standard euclidean space easily with this method. [Vector.basis(3, 0), Vector.basis(3, 1), Vector.basis(3, 2)] => [Vector[1, 0, 0], Vector[0, 1, 0], Vector[1, 0, 1]] ``` This patch is needed in https://bugs.ruby-lang.org/issues/10074 gogo. ---------------------------------------- Feature #10072: [PATCH] Implement Vector.basis https://bugs.ruby-lang.org/issues/10072#change-47906 * Author: gogo tanaka * Status: Open * Priority: Normal * Assignee: * Category: * Target version: ---------------------------------------- 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/
