在MATLAB中同时定义多个变量 [英] Define multiple variables at the same time in MATLAB

问题描述

欲同时以限定多个变量。
例如，我想定义

I want to define multiple variables at the same time. For example, I want to define

a = 1
b = 2
c = 3

这样的。

所以我做了矩阵[A，B，C] ：

x = [a, b, c];

y = [1, 2, 3];

x = y

所以我希望得到如下回答。

So I want to get the following answer.

a = 1
b = 2
c = 3

如果我用

[a, b, c] = deal(1, 2, 3)

那么，我可以得到

then, I can get

a = 1
b = 2
c = 3

不过，我想用矩阵 X 而不是 [A，B，C]

所以，如果我使用，

x = deal(1,2,3)

有一个错误。

请问有什么解决办法吗？

Is there any solution?

推荐答案

也许我不明白的问题，但如果你想使用矩阵 X 而不是 [A，b，C] 为什么你不把它定义为

Maybe I don't understand the question but if you want to use the matrix x instead of [a, b, c] why don't you just define it as

x = [1, 2, 3];

从你的问题听起来我，如果你是过于复杂的问题。你开始想通过申报

From your question it sounds to me as if you are overcomplicating the problem. You begin by wanting to declare

a = 1;
b = 2;
c = 3;

但你想，而不是根据你的问题到底是什么

but what you want instead according to the end of your question is

x = [1, 2, 3];

如果你定义 X 如上可以将参考 x的单个元素像

If you define x as above you can the refer to the individual elements of x like

>> x(1), x(2), x(3)
ans =
     1

ans =
     2

ans =
     3

现在你有1定义两全其美。您可以参考 A ， B 和 C 使用×（1）， X（2）， X（3）来代替，而你只需要定义 X 一旦与 X = [1，2，3];

Now you have the best of both worlds with 1 definition. You can refer to a, b and c using x(1), x(2), x(3) instead and you've only had to define x once with x = [1, 2, 3];.
