如何访问单元阵列矩阵? [英] How to Access the Cell array Matrix?

问题描述

有人能告诉我有关单元阵列的索引的信息吗?我已经尝试过搜索它，但是我只能找到不满意的结果(可能是我在谷歌搜索方面不擅长).对于矩阵索引，我找到了一个很好的文档，可以在此处.就我而言，让我们举一个简单的例子.

Could any one tell me about the indexing of a cell Array? I've tried to google it but I could only find unsatisfied result (may be I'm not good in googling). For matrix indexing I found a good document which can be found here. For my case let take a simple example.

a = {ones(10)}

，我想访问a的第一个元素.像

and I want to access the first element of a. Something like

a(1,1) % this will give a 10 x 10 matrix but i am not looking for it.

我可以通过将其更改为类似矩阵的方式来实现

I can do it by changing it into a matrix like

a = cell2mat(a);
a(1,1)
ans = 1

但是有什么直接方法可以访问单元阵列子矩阵的第一个元素.

but is there any direct way to access first element of cell array sub matrix.

推荐答案

要访问单元格数组中第一个单元格的第一个元素，您可以执行以下操作:

To access the first element of a the first cell in a cell array, you may do:

a = {ones(10)};
a{1}(1)

如果您具有多维单元格数组，并且其中包含多维数字数组，则可以执行以下操作:

If you have multidimensional cell arrays, with multidimensional numerical arrays inside it, you can do:

a{2,3}(4,5)

这将为您提供单元格(2,3)的元素(4,5).

This will give you element (4,5) of cell (2,3).
