I have the nonce value in hex. Let say:
nonce = {'00' '11' '22' '33' '44' '55'};
I need to add any fixed value 'x'(hex) to this value in loop and need to save every new value.
I was doing this like:
nonce = {'00' '11' '22' '33' '44' '55'};
for i=1:5
nonce(i) = nonce + 01;
i = i+1;
end
But I am not acheiving what I need.

Please mention, what you expect as output. Having only not running code does not clarify, what you want to achieve.
Your code contains some bugs:
for i=1:5
nonce(i) = nonce + 01;
% Here on the left side there is a scalar cell element, and on
% the right you try to add 01 (which is the same as 1) to a
% cell vector.
i = i+1; % i is iterated by the FOR loop already
% so do not increase it manually
end

Using a loop:
nonce = {'00' '11' '22' '33' '44' '55'};
x = '01';
for i = 1:numel(nonce)
nonce{i} = dec2hex(hex2dec(nonce{i}) + hex2dec(x),2);
end
Or using cellfun:
nonce = {'00' '11' '22' '33' '44' '55'};
x = '01';
nonce = cellfun(@(y) dec2hex(hex2dec(y) + hex2dec(x),2),nonce,'uni',0);

Well, then an option is:
nonce = {'00' '11' '22' '33' '44' '55'};
x = '01';
a = strcat(nonce{:});
for i = 2:6
a(i,:) = dec2hex(hex2dec(a(i-1,:)) + hex2dec(x),12);
end
nonce = mat2cell(a,ones(6,1),2*ones(6,1))
nonce =
6×6 cell array
'00' '11' '22' '33' '44' '55'
'00' '11' '22' '33' '44' '56'
'00' '11' '22' '33' '44' '57'
'00' '11' '22' '33' '44' '58'
'00' '11' '22' '33' '44' '59'
'00' '11' '22' '33' '44' '5A'
At the end of the code, each row of nonce corresponds with the value in each iteration.

nonce = {'00' '11' '22' '33' '44' '55'};
toAdd = hex2dec('01');
for k = 1:5
nonce{k} = dec2hex(hex2dec(nonce{k}) + toAdd);
end
It might be easier to work with a double vector, if you want to perform calculations. Then hex strings are rather inefficient.
