Notice that fwrite() sends binary data. And note that unless you tell MATLAB otherwise, constants such as 0 and 1 are double precision numbers, which occupy 8 bytes.
Possibly you want
fprintf(s1, '%d', A)
that would send the character string '1' '0' '1' and so on.
You might also want to send a newline to end the line:
fprintf(s1, '\n');

Thanks @walter Roberson for your reply. I used fprintf(s1, '%g\n', A) as you suggested but didn't get any output. I can't paste my whole code here so I open a new question for the same which link I'm giving here. It will be helful for me if you suggest solution to my problem.
Thank you
