Question

我有字符的char数组（向量），我想按特定顺序插入空格。

例如我有

 ['A','B','C','D','E','F','G','H','J','K','L','M','N','O']

带有白色空间索引的矢量

[7 12] % white spaces should be add to 7 and 12 indexes (original string)

并希望拥有

 ['A','B','C','D','E','F',' ','G','H','J','K', 'L', ' ','M','N','O']

是否有一些内置功能？我开始使用嵌套循环来实现数组和instert''，但它看起来很难看。

Answer 1

如果您的向量中有索引，您希望插入空白，则可以执行以下操作：

>> str = 'ABCDEFGHJKLMNO';                %# Your string
>> index = [7 12];                        %# Indices to insert blanks
>> index = index+(0:numel(index)-1);      %# Adjust for adding of blanks
>> nFinal = numel(str)+numel(index);      %# New length of result with blanks
>> newstr = blanks(nFinal);               %# Initialize the result as blanks
>> newstr(setdiff(1:nFinal,index)) = str  %# Fill in the string characters

newstr =

ABCDEF GHJKL MNO

Answer 2

您想在特定索引处插入空格吗？

chars = ['A','B','C','D','E','F','G','H','J','K','L','M','N','O'];
%insert space after index 6 and after index 10 in chars
charsWithWhitespace = [chars(1:6), ' ', chars(7:10), ' ', chars(11:end)];

将空格插入char数组
