2 [0,1,0]
73 [0,1,1,1]
97 1
108 [0,1,1,0]
109 [0,0,0,1]
110 [0,0,0,0]
118 [0,0,1,1]
121 [0,0,1,0]
This is a cell I want the array as 010
0111
1
and so on that is convert it into char for binary purpose

Can you please use valid matlab syntax to describe your input and wanted output?
I think your input might be:
C = {2, [0,1,0];
73, [0,1,1,1];
97, 1;
108, [0,1,1,0];
109, [0,0,0,1];
110, [0,0,0,0];
118, [0,0,1,1];
121, [0,0,1,0]} %This is valid matlab syntax. We can paste this straight into matlab
I have no idea what output you want.
Hello,
Thanks for replying , I want my output as
2, '010'
73 , '0111'
and so on

>> C(:,2) = cellfun(@(v)char(v+'0'),C(:,2),'uni',0)
C =
2 '010'
73 '0111'
97 '1'
108 '0110'
109 '0001'
110 '0000'
118 '0011'
121 '0010'

thanks your code worked , I am new to matlab if you could help me understand the code I would learn a lot.
Thank you so much though
"...if you could help me understand the code I would learn a lot."
I used cellfun to apply a function to each vector:
C(:,2) = cellfun(@(v)char(v+'0'),C(:,2),'uni',0) % my answer, broken down:
% @(v)char(v+'0') % anonymous function [v] -> 'v'.
% C(:,2) % get second column of cell array.
% cellfun( , ,'uni',0) % iterate over each vector (cell content).
%C(:,2) = % allocate to second column of cell array.
Learn more about cellfun and anonymous functions:
The conversion from binary vector to character is by simply adding the character value for '0' (which is 48) onto the binary values and then converting to character. This works for any digits:
>> char([1,2,5,9]+'0')
ans = '1259'
>> char([1,2,5,9]+48) % equivalent
ans = '1259'

Taking a guess here, since you're still not using matlab syntax for your example:
C = {2, [0,1,0];
73, [0,1,1,1];
97, 1;
108, [0,1,1,0];
109, [0,0,0,1];
110, [0,0,0,0];
118, [0,0,1,1];
121, [0,0,1,0]} %demo data
C(:, 2) = cellfun(@(v) char(v + '0'), C(:, 2), 'UniformOutput', false)
