I want to extract 6 lines from a ascii file, and add these lines into another text file which just contains a matrix, like 500*500.
Now, I extract the first 6 lines from the ascii file:
%% extract title for the new ascii file
fid = fopen('filename','r')
numLines = 6; % I knew there are 6 lines I need
title = cell(numLines,1);
for ii = 1:numLines
title(ii) = {fgetl(fid)};
end
fclose(fid);
Q1: how to combine these lines with another matrix to generate a new text file?
Q2: how to output this new text file?
Any help would be appreciated.

Read about fprintf and dlmwrite. First write the text lines and then write the matrix.

Could you please comment more on this question, I do appreciate it.
The title should be like this:

and honestly, this text file contains a matrix, which is a 5000*5000. (So, one of my thought is whether I can replace this 5000*5000 matrix only by another 5000*5000 matrix, and then output this new hybrid text?)
Another text file just contains a 5000*5000 matrix.

Yeah, it seems that what you (KSSV) said is the only way to address the problem.
Now, the problem has been solved by your thought.
Thanks again.
