This prints my 6 sets of data as one continuous column of data in a .txt file.

fileID = fopen('nN_10.txt','w');
fprintf(fileID,'%.8f\r\n',X(:,1), X(:,2), X(:,10), X(:,4), X(:,5), X(:,6));
fclose(fileID);

That's fine, I would just like to insert one blank line between each set of data. I imagine the solution is particularly easy but I can't seem to find it anywhere!

Thanks.

在 MATLAB Online 中打开

Try this:

fprintf(fileID, '%f\n', x(:,1));
fprintf(fileID, '\n');
fprintf(fileID, '%f\n', x(:,2));
fprintf(fileID, '\n');
fprintf(fileID, '%f\n', x(:,3));
fprintf(fileID, '\n');
fprintf(fileID, '%f\n', x(:,4));
fprintf(fileID, '\n');
fprintf(fileID, '%f\n', x(:,5));
fprintf('\n');
fprintf('%f\n', x(:,6));
fprintf('\n');

Also, open the file as 'wt' instead of 'w'. You can probably get rid of the \r then also, but maybe not - it depends on what you use to open the file with (e.g. notepad or wordpad).
