T1=[T1 count]
datahex = sprintf('%02x', T1)
I don't know why output in that format],T1 is character

First, if there are spaces in your T1 string, get rid of them:
T1(T1 == ' ') = []; %remove spaces
For demo purpose:
T1 = char(randi(double(['0' '1']), 1, 128)); %random demo string of 128 '0' and '1'
Then, assuming that the length of T1 is a multiple of 8:
datahex = num2cell(lower(dec2hex(bin2dec(reshape(T1, [], 8)))), 2)'
Basically, reshape your string into columns of 8 characters. Convert each row from binary string to decimal number and then from decimal number to hexadecimal string. Optionally, convert to lowercase and cell array.

Doh! Sorry, should have tested and thought through the code better.
Reshape into 8 rows and transpose, rather than 8 columns:
datahex = num2cell(lower(dec2hex(bin2dec(reshape(T1, 8, [])'))), 2)'

Radwa - your T1 is a string of characters, so the zeros and ones are characters. The ASCII code for a character 0 and character 1 is 48 and 49 respectively. The hexadecimal equivalent of each is 30 and 31, so your above answer makes sense. (The 29 would be for the space character.)

I don't understand your format. How does your input string translate to that? There are limitations to the size of integers that you can use with these functions, and if you insist on using 128 bits, you may need to create a class that can handle a data type of that size.
