how to delete column from text file without loading it into a matrix first

I have the code as follows:

fid = fopen('5_prcnt_noised_iono_train_data.txt','w+');

    for i = 1:Ntrain_data
        fprintf(fid,'\n%6.2f',noised_train_data(i)); 

        for j = 1:Nof_noised_train_feat
              fprintf(fid,'\t%6.2f',noised_train_data(i,j));

        end
    end

in this , I have write the train data into a text file from train_data matrix.... The problem is, when writing the data in the text file,it also print an extra first column in the start of each row....and I don't want this extra first column....

I have to delete that column but the format of fprintf func does not allow me to do this.....

There is need to make change in the 3rd line of code:

        fprintf(fid,'\n%6.2f',noised_train_data(i));

this syntax add an extra first column in each row.....

how to fix it??..

Change it to

fprintf(fid,'\n');

but when I open the text file it doesn't show me the next row in new line it continues to the same row.. Although, when I open this text file via MATLAB editor it shows me the next row in new line correctly....

I also wants the same with when I open the text file without MATLAB editor.............

Actually, I have to use this text file further in my code so, I need to keep the data in an arranged format
