水平串联字符串的单元格数组

问题描述：

我希望水平连接字符串单元格数组的行，如下所示.

I wish to horizontally concatenate lines of a cell array of strings as shown below.

start = {'hello','world','test';'join','me','please'}

finish = {'helloworldtest';'joinmeplease'}

是否有内置函数可以完成上述转换?

Are there any built-in functions that accomplish the above transformation?

答

一种简单的方法也是在行上循环

A simple way is too loop over the rows

nRows = size(start,1);
finish = cell(nRows,1);

for r = 1:nRows
    finish{r} = [start{r,:}];
end

一种更复杂，更难读的解决方案(一般解决方案留给读者练习)

A more involved and slightly harder to read solution that does the same (the general solution is left as an exercise for the reader)

finish = accumarray([1 1 1 2 2 2]',[ 1 3 5 2 4 6]',[],@(x){[start{x}]})
