i am getting an error
Error using horzcat
CAT arguments dimensions are not consistent.
Error in text_fin1 (line 69)
fprintf(f,'%d;%i64;\n',[q d]);

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)]')

i need for column vectors

the column vectors are not of equal size

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

i used this code
fprintf(f, '%i24;\n',d,'%d;\n',q);
i am getting values of q after values of p i need them beside each other.

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')
