如何在一行中使用`textscan`函数的多个输出? [英] How do I consume multiple outputs of `textscan` function in a single line?

问题描述

假设我有以下字符串:

s ='Foo 1.000 3.000 3.554'

s = 'Foo 1.000 3.000 3.554'

我想用textscan函数按如下方式阅读它.

I would like to read it with the textscan function as follows.

[name x y z] = textscan(s，'％s％f％f％f')

[name x y z] = textscan(s, '%s %f %f %f')

但是，当我这样做时，总是会出现Too many output arguments错误.

However, when I do this, I always get the Too many output arguments error.

我认为这与textscan输出一个单元格数组有关，但是我找不到解决该问题和所需效果的方法.

I think it has to do with the fact that textscan outputs a cell array, but I could not discover how to work around this problem and the desired effect.

推荐答案

您将需要两行来完成所需的操作.首先，将所需的值转换为虚拟变量，然后使用deal分配数据:

You'll need two lines to do what you want. First you get the desired valued into a dummy variable, then distribute the data with deal:

dummy = textscan(s, '%s %f %f %f');
[a,b,c,d] = deal(dummy {:});
