Line 15: :Also, note that negate and either add or subtract could be defined in terms of the remaining operations. :I hope this helps. --[[User:Rdm\|Rdm]] ([[User talk:Rdm\|talk]]) 06:19, 22 March 2015 (UTC) :I think the number of components probably should be explicitly defined in the description, although if the task will definitely not extend beyond the basic operators it may be ok to allow a variety. Many operations extend to n-dimensional space but cross and triple product for example do not. Even between 2 and 3 dimensions cross product is completely different, usually a wedge product is used as an equivalent in 2 dimensions. Also implementations of operations can differ significantly based on the number of components, normal vectors for example (perpendicular surface normals). --[[User:dotxor\|dotxor]] ([[User talk:dotxor\|talk]]) 14:16, 7 August 2015 (UTC) ==Duplication?== Line 24 ⟶ 26: :It's not a duplication of [[Vector products]]. It's far closer to [[Arithmetic/Complex]]. --[[User:Rdm\|Rdm]] ([[User talk:Rdm\|talk]]) 06:20, 22 March 2015 (UTC) =="Physical Vector?"== What is a "physical vector"? Shouldn't it be 3-dimensional? [[User:Peak\|Peak]] ([[User talk:Peak\|talk]]) 22:59, 17 May 2015 (UTC) : A physical vector is a sequence of numbers which represents some real (or physical) thing. For example, a physical vector might represent the speed a car is traveling, as well as the direction it is traveling. --[[User:Rdm\|Rdm]] ([[User talk:Rdm\|talk]]) 13:44, 7 August 2015 (UTC) =="Specification"== I miss specification from the user that created each task. I mean Input -> function -> Output So with a defined input you should also get a defined output. Of course the same in all languages. Now it is not strict at all. --[[User:Bero\|Bero]] ([[User talk:Bero\|talk]]) 16:09, 25 April 2020 (UTC)
