Removing automatic variable names in array2table or writetable and adding some text to the header of output file

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.

Try this

T=array2table(Output, 'VariableNames', {'DR1', 'DR2'}); % or whatever variable names you like to set

Thanks for your comment. Is there any way to remove the variable names first? Then there would be some way to add a single header to the text file possibly altering the writetable.

What I get in the text file is:

DR1 DR2

169 30

178 26

234 26

What I need is:

DR

169 30

178 26

234 26

Then don't use a table with two variables but an array instead.

T=table([DD,D],'VariableNames',{'DR'});

Again the solution gives:

DR_1 DR_2

169 30

178 26

234 26

I found a way to remove the variable names: 'WriteVariableNames',false in writetable handles.

What I need now is to add a DR to start of the text file.

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'});
