Matlab: convert array of number to array of strings
提问by olamundo
How can I convert [12 25 34 466 55]to an array of strings ['12' '25' '34' '466' '55']? The conversion functions I know convert that array to one string representing the entire array.
如何转换[12 25 34 466 55]为字符串数组['12' '25' '34' '466' '55']？我知道的转换函数将该数组转换为代表整个数组的一个字符串。

An array of strings has to be a cell array. That said:
字符串数组必须是元胞数组。那说：
s = [12 25 34 466 55]
strtrim(cellstr(num2str(s'))')
回答by Kavka
Using arrayfuntogether with num2strwould work:
使用arrayfun连同num2str将工作：
>> A = [12 25 34 466 55]
A =
12 25 34 466 55
>> arrayfun(@num2str, A, 'UniformOutput', false)
ans =
'12' '25' '34' '466' '55'

Now after MATLAB 2016b, you can simply use
现在在 MATLAB 2016b 之后，您可以简单地使用
s = [12 25 34 466 55];
string(s)

Starting from R2016b there is also the compose function:
从 R2016b 开始，还有 compose 函数：
>> A = [12 25 34 466 55]
A =
12 25 34 466 55
>> compose("%d", A)
ans =
1×5 string array
"12" "25" "34" "466" "55"'''
回答by Vish
In MATLAB, ['12' '25' '34' '466' '55'] is the same as a single string containing those numbers. That is to say:
在 MATLAB 中， ['12' '25' '34' '466' '55'] 与包含这些数字的单个字符串相同。也就是说：
['12' '25' '34' '466' '55']
ans =
12253446655
I need more context here for what you are trying to accomplish, but assuming you want to still be able to access each individual number as a string, a cell array is probably the best approach you can take:
我需要更多上下文来了解您要完成的任务，但假设您仍然希望能够将每个单独的数字作为字符串访问，那么元胞数组可能是您可以采用的最佳方法：
A = [1 2 3]
num2cell(num2str(A))
(Of course, you'd still have to remove the stray spaces from the ans)
（当然，您仍然必须从 ans 中删除杂散空间）
