How to print arrays of strings to the txt file with spaces and new lines?

I have a problem with printing an array of strings, which I'd like to print to a txt file. The problem is I can't put spaces between elements. My new lines don't work neither.

Here's a snipped of my code:

out3 = fullfile('D:\new.txt');
fid1 = fopen(out3,'a');
for i = 1:Numb_of_folds
   
    pattern = nameFolds1(i);
    TF = startsWith(files,pattern);
    Z = files(TF);
    Z = cellstr(Z.');
    
    fprintf(fid1,'\n');
    fprintf(fid1,'%s %s\n\r %s',Z{:});
    fprintf(fid1,'\n');
    %fprintf(fid1,'%s\n\r',pattern);
    %fclose(fid1);
end
fclose(fid1);
winopen(out3)

'Numb_of_folds' - number of times I need to begin from the new line.

The 'files' variable is array of strings which I need to print.

I am checking if some of them begins with the specified pattern, we print on one line.

The problem is it prints it like :

DYT01_OFF DYT02_OFF DYT03_OFFDYT04_OFF DYT06_OFF DYT07_OFFDYT13_OFF

These two strings I use, but I don't know why. I just read that I need this.

Z = cellstr(Z.');

Z{:}

On windows machine you should use "\r\n" for new line and for tabs you can use "\t"

[Walter Roberson]

Alternately, instead of opening

fid1 = fopen(out3,'a');

you can

fid1 = fopen(out3,'at');

If you do that, then on WIndows machines, each \n you output will be automatically translated to \r\n
