How to auto change save file name with For loop

I am looking for how to auto change save file name with For loop

N = 6;
for k = 1:N
F = sprintf('RR.data.%u',k);
C{k} = dlmread(F)
data = vertcat(C{:});   % <-- data is input

% After processing
%
% processing output is result
result = output % <-- how to auto change save file name with For loop

The result files overlap. that is why i ask

I don't understand your question. Your code doesn't save anything. On the other hand, you're reading files whose name you're already changing.

It's also unclear why the vertcat(C{:}) is inside the k loop and what 'output of data' mean.

Do you mean this?

result(k) = output
