function handles to save data

I want to save the Output for every round my loop takes. The Problem; I need an handle and my m-file has no Objects. The Question: How do i define a handle which i can use to store my data.

Max - why do you need a handle? Is your Output the same dimension on each iteration of the loop? If so, then consider using a matrix to store the data from each iteration. If not, then use a cell array.

ok, help me pls. I store each loop "round" in 1 array row. So how do i get an empty 1x9 Array ?

i will go home, sleep 12hours and work again tomorrow. thanks

Max - try the following. Suppose the output from one iteration of your loop is a 1x9 vector, and that there are 25 iterations. That means we need a 25x9 matrix:

 maxIters = 25;
 allData  = zeros(maxIters,9);

 for k=1:maxIters

     % do some work that results in a 1x9 vector
     output = ones(1,9);

     % save the output to the kth row of the allData matrix
     allData(k,:) = output;

 end

And that is it. Once outside of the for loop, allData has the output from each iteration.

Try the above and see what happens!
