How to save, for loop

Example:

for i=1:n X=DATA1(i,1); Y=DATA2{1,i}; Z=X-Y;

end

what I want is that it saves the data to Z, summing them, so, for i=1 , Z=[1 2 3 4 5], for i=2 Z becomes Z=[1 2 3 4 5 6 7] etc.

so i need to do something with Z but dont know what. currently it only shows the result of the last i.

Do you really have X as a numerical array (double, etc.) and Y as a cell array???

 for i=1:n,
    X = DATA1(i,1); %% DATA1 is an array
    Y = DATA2{i,1}; %% DATA2 is a cell
    Z(i,:) = X-Y;
 end
 save Z

or

 Z = DATA1 + cell2mat(DATA2);
 save Z

the first one works if both X and Y are matrix ( ()) but if Y is cell array {} then it gives trouble. Somehow I need to convert Y to matrix then put it in the equation.

I look into the second tip

thank you
