try this Minu y= {'0D05','0D06','0D10'};

if u want to update the array during run time

y{i} = {str};

[Minu]

When i tried this i have got this error "Cell contents assignment to a non-cell array object."

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'

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.
