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.

Accepted answer

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

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

yes x= column full of values (nummerical array) and Y cells , with each cell with diff lengths
