我该怎么做在MATLAB多重分配？ [英] How do I do multiple assignment in MATLAB?

问题描述

下面是一个例子就是我在寻找：

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

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

我的期望的像这样算账：

>> x

x =

    88

>> y

y =

    12

而是我得到这样的错误：

But instead I get errors like:

??? Too many output arguments.

我觉得交易（）可能做到这一点，但它似乎只对细胞的正常工作。

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.

我如何解决我的问题？我必须不断地被1和2的索引，如果我想单独对付他们？

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

您不需要交易在所有（编辑：Matlab的7.0或更高版本），对于你的榜样，你不需要 mat2cell ;您可以使用 num2cell 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

如果你想使用交易某些其他原因，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
