Hi,

I have a loop which generate for every run a string output (loop size index is changing depends on how much files are in the directory). How can I concatenate the string output to another string vertically/send them into char/etc so I can save the final output (all the string output results) to a one text file?

Any idea is welcome.

Thanks.

Note - strvcat will eventually be removed from MATLAB. It is recommended in MATLAB documentation to use char instead. Also, it would be better to perform the concatenation after the loop (storing the strings in cells) so that s doesn't grow iteratively.

Assuming you've read the strings into a cell array you can use CHAR to concatenate them, e.g.,

>> char({'car','apple'})
ans =
car  
apple

But it will only save the last string, not all of them-

Clarify what part of your code you're talking about (and show it). You should be able to see in my example that char({'car','apple'}) gave you both strings in its output, not just the last one.
