如何在MATLAB中从总数N中获得K个项目的所有可能组合 [英] How to get all possible combinations of K items from a total of N in MATLAB

问题描述

例如，如果[1,2,3,4,5,6]是向量，则一次3个项目的所有可能组合为

For e.g., if [1,2,3,4,5,6] is a vector, then all possible combinations of 3 items at a time is

 4     5     6
 3     5     6
 3     4     6
 3     4     5

如何在MATLAB中找到它?

How do I find this in MATLAB?

推荐答案

尝试一下链接.基本上，您只需要键入c = combnk(1:6,3).希望对您有所帮助.

Try this link. Basically you just need to type c = combnk(1:6,3). Hope it helps.

我提出的建议和@nash的combntns之间的区别是命令所在的工具箱.combnk在统计信息"工具箱中，而combntns在映射工具箱"中.

The difference between what I proposed and @nash 's combntns is the toolbox that the commands are in. combnk is in the Statistics Toolbox, while combntns is in the Mapping Toolbox.
