I have entered the following commands on matlab command window and its working.
>> y= {'0D05','0D06','0D10'}; >> i = 4
i =
4
>> y{4} = '0D11'
y =
'0D05' '0D06' '0D10' '0D11'

@Minu: Please care for always posting a complete copy of the message accompanied by the relevant part of the corresponding code. Without seeing the code, we would have to guess suggestions for improvements. Thanks.

You cannot access a string with y(1) easily. The problem is that your data is a character array and not a string array. This means that the notation y(1) is asking for a single element of a character array, which is a single character, but you want a string.
Assuming you are starting with some data that looks like
x = char(randi([1, 26]+64, 1, 4*10))
You can rearrange it to have the shape you want by putting 4 characters on a row.
y = reshape(x, [], 4);
You can then get a row with
y(1, :)
If you do not want the trailing colon, you could use a cell array
z = mat2cell(y, ones(10, 1), 4);
You can then get a row with
z{1}
If neither of these suffice you can use the OOP system to define your own string class and then you can use y(1) to get a single element of a string object which would be a character array.

y=char('0D05','0D06','0D10');
%or
y=cellstr(char('0D05','0D06','0D10'));

In the first case, char can be omitted and replaced by square brackets. In the second case char can be omitted without any replacement.
