IV={'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '01'}

The expected output is:

IV={'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '02'} ie only incrementing the value at the end??

What must be the matlab code?

IV = {'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '01'};
y =  {'00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '01'};
x_numeric = cellfun(@(x) sscanf(x, '%x'), IV);
y_numeric = cellfun(@(x) sscanf(x, '%x'), y);
xplusy_numeric = x_numeric + y_numeric;
xplusy_cell = sprintfc('%02x', xplusy_numeric);

... I predict you are going to change the question once you think about this for a few minutes.

Sir, Actually i wanted to increment the cell array, IV, such that the output will be as follows:

IV 1= {'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '01'};
IV 2 = {'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '02'};
IV 3 = {'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '03'};

and so on. Thanks for the reply.Is there a simpler way??

IV = {{'ca' 'fe' 'ba' 'be' 'fa' 'ce' 'db' 'ad' 'de' 'ca' 'f8' '88' '00' '01'}};
y =  {'00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '00' '01'};
x_numeric = cellfun(@(x) sscanf(x, '%x'), IV{1});
y_numeric = cellfun(@(x) sscanf(x, '%x'), y);
for K = 2 : 3
   x_numeric = x_numeric + y_numeric;
   IV{K} = sprintfc('%02x', x_numeric);
end
