在Matlab中将变量命名为字符串 [英] Name a variable as string in Matlab

问题描述

假设变量FileName包含一个字符串，例如Name1.如何创建名称为Name1的变量?

Assume the variable FileName contains a string such as Name1. How do I make a variable with the name Name1?

此页面上的示例4似乎很相似，但是我无法使其正常工作.这是正确的方法吗? http://se.mathworks.com/help/matlab/ref/genvarname.html

The example 4 at this page seems to be similar, but I cant get it to work. Is it the right way to do it? http://se.mathworks.com/help/matlab/ref/genvarname.html

推荐答案

对于您要执行的操作，eval函数可为您提供:

For what you want to do, the eval function is there for you:

FileName = 'Name1';
eval([FileName ' = 18;']);      % Executes "Name1 = 18;"

，现在已创建变量Name1，其值为18.

and now the variable Name1 is created and has a value of 18.

函数genvarname具有不同的用途，即生成可接受且无冲突的变量名称，而不是变量本身.

The function genvarname has a different purpose, which is to generate acceptable and non-conflicting variable names, and not the variables themselves.
