We cannot generalize your program, we we do not see it. So please post your code, when you want us to help.

Did you search in the FileExchange already? This would be a good idea before asking the forum. What about http://www.mathworks.com/matlabcentral/fileexchange/10064-allcomb?

A=[1 6]; B=[2 3 4]; C=[8 9];
Use function fullfact from Statistics Toolbox.
for your case:
t = {A,B,C};
k = cellfun(@numel,t);
ii = fullfact(k);
idx = bsxfun(@plus,ii,cumsum(k) - k);
s = [t{:}];
comb = s(idx);
comb = reshape(sortrows(comb)',1,[]); % ADD
