Matlab中的补集子集 [英] Complement subset in Matlab

问题描述

在R中，我可以执行以下操作:

In R, I can do the following:

v <- 11:20
v[-(4:5)]

并获得11 12 13 16 17 18 19 20，因此所有索引 均排在第4位和第5位.

and get 11 12 13 16 17 18 19 20, thus all indices except the 4th and 5th.

Matlab的索引逻辑是否等效?

Is there an equivalent in Matlab's indexing logic?

但是我全神贯注于此，对于这个相当基本的问题，我似乎没有找到正确的搜索词来搜索我自己的结果.

However I wrap my mind around it, I do not seem to get the correct search terms to google my own result for this fairly elementary question.

注意:当然，我可能会使用某些设置函数，例如

Note: Of course I might use some of the set functions, e.g.

v = 11:20;
v(setdiff(1:length(v), 4:5))

但是，这只是不直观的.

However, this just is not intuitive.

推荐答案

另一种方法是简单地从数组中删除元素:

An alternative is to simply remove the elements from the array:

u = v;
u(4:5) = [];

我正在使用一个临时变量，因为我不知道修改原始数组v是否可接受.

I'm using a temporary variable since I don't know if it's acceptable to modify the original array v or not.
