how can i restore data which is replaced in the end

% 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

@Stephen23 sir, just suggest me how can i restore Utt for all value of n without replacing. which i can call for further use.

" how can i restore Utt for all value of n without replacing"

Include the n index into your output array.

[Image Analyst]

"how can i restore Utt for all value of n" << try

UttCopy = Utt;
% for loop code, then
% Restore Utt for all n
Utt = UttCopy;

[Chaudhary P Patel]

Utt=UttCopy;

Sir, this command is not working.

it is replaced by the end value of n.

Either add n as an index to the array, or else do calculations similar to the d1 d2 to determine where to write into.

My recommendation would be to use the extra index

@Walter Roberson, how can i use extra index sir?
