matlab: convert char array into string
提问by user1822048
I implemented a bash script in matlab, which returns a char array with all the outputs (echo). Now I would like to use the data stored in the array, to open a file. Unfortunately, I don't know how to convert the array into a string. The following code works:
我在 matlab 中实现了一个 bash 脚本，它返回一个带有所有输出（回声）的字符数组。现在我想使用存储在数组中的数据来打开一个文件。不幸的是，我不知道如何将数组转换为字符串。以下代码有效：
[status, output] = system('./script.sh', '-echo');
filename = [ output(1) output(2) output(3) output(4) output(5) output (6) ];
But it is not very convenient and doesn't allow different lengths of the filename. Is there an easy way to solve this?
但它不是很方便，并且不允许不同长度的文件名。有没有简单的方法来解决这个问题？

Basically, character arrays arestrings; there's no need to convert them.
基本上，字符数组是字符串；没有必要转换它们。
filename = output
should do the trick.
应该做的伎俩。
