Hello. So I have an input file which is a matrix in formatted form. Now I want to do some operations to change a couple of rows of the matrix and then output the new matrix to another file.

Here I load original file into a matrix (feat), and integers (nb and dim) :

[feat nb dim] = loadFeatures([dataset_dir,Lname{i},'/img',num2str(j),'.mser']);

These are the operations I perform on the matrix feat to insert new values:

          var1 = feat(3);
          var2 = feat(4);
          var3 = feat(5);
          t1 = var3-var1;
          t2 = (t1 + sqrt(t1.^2 + 4*(var2.^2))/2*var2);
          th = atan(t2);
          sc = 1;

Now, what I want to do is along with the first 2 rows of the natrix(feat), I want to store a row (th) and sc( a vector filled with the value sc):

for ii = 1:size(1,nb)
            fprintf(fid,'%g\t',feat(1,ii),feat(2,ii),sc,th(ii));
            fprintf(fid,'\n');
        end
        fclose(fid)

However, all this does is store the values for only one column. The rest of the columns are somehow ignored.

I am stuck here, and desperately need to figure this out. Any help here would be appreciated. Thank you for your patience.

在 MATLAB Online 中打开

fprintf(fid,'%g\t',feat(1,ii),feat(2,ii),sc,th(ii));
%replaced by 
fprintf(fid,'%g\t%g\t%g\t%g\t',feat(1,ii),feat(2,ii),sc,th(ii));

I tried that and I am still getting a single line (single column) as output. As before. I tried outputting some of the matrices ( feat) and they all output the result they're supposed to. I do not know what else to check for here.
