什么是 m 元向量?
我正在观看有关线程的讲座,他们使用术语m-ary向量
如下:
"Let [X] represent an m-ary vector of non-negative integers"
这是什么?数量是长度吗?我认为向量只是像数组一样的顺序数据结构?为什么要使用字母m
- 我以前只见过n-ary
。
I am watching a lecture on threading and they use the term m-ary vector
as follows:
"Let [X] represent an m-ary vector of non-negative integers"
What is this? Is the arity the length? I presume a vector is merely a sequential data structure like an array? Why would the letter m
be used - I have only ever seen n-ary
previously.

是的。
是的。
有二十六个拉丁字母可以使用。如果稍后他们要讨论两个不同长度的向量,他们将需要不同的字母。
Yes.
Yes.
There are twenty-six latin letters that could be used. If -- later -- they are going to talk about two different length vectors, they're going to need to different letters.
