创建具有字符串名称的变量 [英] Create variables with names from strings

问题描述

假设我想创建 10 个变量，它们看起来像这样:

Let's assume that I want to create 10 variables which would look like this:

x1 = 1;
x2 = 2;
x3 = 3;
x4 = 4;
.
.
xi = i;

这是我打算做的简化版本.基本上我只想通过以自动方式创建这些变量来保存代码行.是否有可能在 Matlab 中构造变量名?我的示例中的模式是 ["x", num2str(i)].但是我找不到创建具有该名称的变量的方法.

This is a simplified version of what I'm intending to do. Basically I just want so save code lines by creating these variables in an automated way. Is there the possibility to construct a variable name in Matlab? The pattern in my example would be ["x", num2str(i)]. But I cant find a way to create a variable with that name.

推荐答案

你可以用 eval 但你真的应该不

You can do it with eval but you really should not

eval(['x', num2str(i), ' = ', num2str(i)]); %//Not recommended

不如使用元胞数组:

x{i} = i
