我想生成给定数量的向量的元素的所有可能组合.
例如,对于[1 2],[1 2]和[4 5],我要生成元素:
[1 1 4; 1 1 5; 1 2 4; 1 2 5; 2 1 4; 2 1 5; 2 2 4; 2 2 5]
问题是我不知道计算组合所需的向量数量.在这种情况下,可能有3个,或者可能有10个,我需要 generalization .您能在MATLAB中帮助我吗?已经有可以执行此任务的预定义功能吗?
解决方案在FileExchange尝试 ALLCOMB 函数. /p>
如果将向量存储在单元格数组中,则可以这样运行它:
a = {[1 2], [1 2], [4 5]}; allcomb(a{:}) ans = 1 1 4 1 1 5 1 2 4 1 2 5 2 1 4 2 1 5 2 2 4 2 2 5I would like to generate all the possible combinations of the elements of a given number of vectors.
For example, for [1 2], [1 2] and [4 5] I want to generate the elements:
[1 1 4; 1 1 5; 1 2 4; 1 2 5; 2 1 4; 2 1 5; 2 2 4; 2 2 5]
The problem is that I don't know the number of vectors for which I need to calculate the combinations. There might be 3 as in this case, or there may be 10, and I need a generalization. Can you please help me to this in MATLAB? Is there already a predefined function that can do this task?
解决方案Try ALLCOMB function at FileExchange.
If you store you vectors in a cell array, you can run it like this:
a = {[1 2], [1 2], [4 5]}; allcomb(a{:}) ans = 1 1 4 1 1 5 1 2 4 1 2 5 2 1 4 2 1 5 2 2 4 2 2 5
