fprintf(fid, '%d;%d;\n', [A B]')
Please read the documentation to understand how a function works. The documentation can be really bad sometimes (accumarray comes to mind), but for fprintf() it is rather decent.

This works if q and d are row vectors of equal size
fprintf(f,'%d;%i64;\n',[q' d']);

I guess you could make it foolproof:
fprintf(fid, '%d;%d;\n', [reshape(A,[],1) reshape(B,[],1)]')

Then you can't do it like that. What do you want the output to be when there is only one value.

Filling with NaN, when there are no values:
A = rand(10,1);
B = rand(15,1);
nRows = max([numel(A) numel(B)]);
your_mat = nan(nRows,2));
your_mat(1:numel(A),1) = A;
your_mat(1:numel(B),2) = B;
%...
fprintf(fid, '%d;%d;\n', your_mat')
