Save each loop values, without overwriting

How can I save each loop values without overwriting

Answer 1

for i=1:10
a(i)=.....  %using array
end 

Here value will not replace, values save as a(1), a(2).. etc

How do I do this if I want a list of files but not an array of values?

Cell array

[Chaudhary P Patel]

% I am facing the that Utt for n=5 replacing the others, so I am unable to call the previous value of Utt for n=1,2,3, and 4 .
for i=1:1:10
    for n=1:1:5
        if n==1 
            Utt(:,i+1)=([zeros(3,1); utdelt(1:3,i+1)]);   % utdelt (15X10)
        else
            d1=1+(n-2)*3;  
            d2=6+(n-2)*3;
            Utt(:,i+1)=utdelt(d1:d2,i+1);
        end
    end 
end
% end of the loop Utt is only saved for n=5, how can i save all the value
% of Utt for n=1,2,3,4 also.

https://www.mathworks.com/help/matlab/matlab_prog/preallocating-arrays.html - essential for a loop and see how the variables are indexed using loop iterator.
