变量名Matlab中的循环字符串 [英] Loop String in variable name Matlab

问题描述

我想创建变量并通过循环索引将变量命名为变量名称

I would like to create variables and name the variables through an index in a loop into the name of the variable

for k = 1 : 10
    A_{k} = rand(10,1);
end

我希望它创建变量

A_1 = [.43,.234.,....]
A_2
A_3
...

但事实并非如此.它只会创建一个变量A.

But it doesnt. It only creates an variable A.

如何将索引输入循环以创建单个变量?

How do I feed the index into the loop to create individual variables?

推荐答案

您可以使用分配，如下所示:

You can make variables dynamicly, using assignin, as follows:

for k = 1:10
    assignin('base', ['A_', num2str(k)], rand(10,1))
end
