Assignee set to Marc-Andre Lafortune Looks good. I think the short description is probably good enough. The example makes it clear if someone has doubts... I'm travelling, will commit in a few days. ---------------------------------------- Feature #13208: Vector.zero(n) and vector.zero? https://bugs.ruby-lang.org/issues/13208#change-62958 * Author: Chia-sheng Chen * Status: Open * Priority: Normal * Assignee: Marc-Andre Lafortune * Target version: ---------------------------------------- Found that I need this recently, and class `Matrix` has these two function while `Vector` not. So I add two function based on `Matrix` counterpart and also add test. Usage ``` ruby require 'matrix' v = Vector.zero(3) # => Vector[0, 0, 0] v.zero? # => true w = Vector[1, 0, 0] w.zero? # => false ``` ---Files-------------------------------- 0001-Add-Vector.zero-n-and-vector.zero.patch (2.06 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
