Hello again,
second question from me today, albeit not quite as complex as the previous.
I have created an array of 8 bit binary groups in the format: '195 x 8 char array'
My intention is to output these to a file, so a second remote user can import them in the same format. Currently, using the formatting operators, I am unable to do so. The closest I have come to achieving my goal is a single concananated string.
I want to write the 8 bit binary groups to a file called 'ENCODE OUTPUT', the binary groups are arranged vertically as follows:
'00101111'
'00101111'
'01110010'
and so on...
My code is as follows:
fid =fopen('ENCODE OUTPUT.txt', 'wt' );
fprintf(fid, '%s,8\n', binX);
fclose(fid);
binX is the variable that contains the entire binary data.
Please accept my apologies if my terminology is off, and thank you for any assistance you can offer.

You don't need fopen, fprintf, or fclose. A simple script like this will do the trick:
binX = ['00101111'; '00101111'; '01110010'];
writematrix(binX, 'yourfile.txt');
