Hi all,
I'm writing a code and I would save the result in a specific line of text file. for example, the code should write the result on .txt file from line 6 or 7 but I don't know how can I do it. I've used
fid = fopen('z.txt', 'w');
fprintf(fid, '%d\r\n',MyResult);
fclose(fid)
But it can just write in a new line no each line as I want. Could you please help me

If you want to append lines, read the doc. If you want to do something else, you'll have to explain it more, preferably with some examples, because right now, I don't know if I understand you.

Use the append switch in fopen, fprinft an empty line, and fprintf the matrix with the FormatSpec of your choosing.
