Hi, I am trying to get a text output file using the following code:
Output=[DD,D];
T=array2table(Output);
writetable(T,'m.txt','Delimiter',' ')
I get the variable names Output1 and Output2 as headers in the output text file. I would like to remove both names and instead have a text like DR as the heading.

Finally I found that fprintf is a better fuction for my purpose:
fid=fopen('m1.txt', 'w'); % open a file for writing
fprintf(fid,'DR\n'); % print a title
fprintf(fid,'%d %d\n',Output); % print values in column order % two values appear on each row of the file
fclose(fid);
Thanks all.

As @Ive J points out, define variable names as desired. NB there's no need for intermediate variables here, either--if you already have the variables, then just use them directly:
T=table(DD,D,'VariableNames',{'DR1','DR2'});
