如何在 MATLAB 中进行多重赋值? [英] How do I do multiple assignment in MATLAB?

问题描述

以下是我正在寻找的示例:

Here's an example of what I'm looking for:

>> foo = [88, 12];
>> [x, y] = foo;

我会期待这样的事情:

>> x

x =

    88

>> y

y =

    12

但是我得到了如下错误:

But instead I get errors like:

??? Too many output arguments.

我认为 deal() 可能会这样做，但它似乎只适用于单元格.

I thought deal() might do it, but it seems to only work on cells.

>> [x, y] = deal(foo{:});
??? Cell contents reference from a non-cell array object.

我该如何解决我的问题?如果我想分别处理它们，我必须不断地索引 1 和 2 吗?

How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

推荐答案

您根本不需要 deal(对于 Matlab 7.0 或更高版本)，例如，您不需要不需要mat2cell；你可以使用 num2cell 而没有其他参数::

You don't need deal at all (edit: for Matlab 7.0 or later) and, for your example, you don't need mat2cell; you can use num2cell with no other arguments::

foo = [88, 12];
fooCell = num2cell(foo);
[x y]=fooCell{:}

x =

    88


y =

    12

如果您出于其他原因想使用 deal，您可以:

If you want to use deal for some other reason, you can:

foo = [88, 12];
fooCell = num2cell(foo);
[x y]=deal(fooCell{:})

x =

    88


y =

    12
