how to perform bitwise logical xor for two matrices having 13 bit binary data each?

I have two cell arrays with each element having 13 bit binary strings. How to perform bitwise XOR for these two cell arrays.
For eg: consider two 3x3 cell arrays A and B
A= '1011111111011' '1011111111011' '1011111111011'
'1100000111111' '1100000111111' '1100000111111'
'1100000001000' '1100000001000' '1100000001000'
B= '1100001001010' '1100001001010' '1100001001010'
'1011111100010' '1011111100010' '1011111100010'
'1100000001110' '1100000001110' '1100000001110'
My desired output is as below
C=A XOR B
ie C(1,1)= '1011111111011' XOR '1100001001010'
C(1,1)= '0111111011001'
Similarly for all the elements a bitwise XOR should be performed

Your example shows two cell arrays containing strings (made up of characters '0' and '1'), not two matrices containing binary data (which is a just numbers)
So, do you have matrices or cell arrays, and do they contain strings or numbers?
Ive edited the qn sir....

Assuming that what you have are cell arrays of strings, and you want to output a cell array of string as well, this would be one way to do it:
A = {'1011111111011' '1011111111011' '1011111111011'
'1100000111111' '1100000111111' '1100000111111'
'1100000001000' '1100000001000' '1100000001000'};
B = {'1100001001010' '1100001001010' '1100001001010'
'1011111100010' '1011111100010' '1011111100010'
'1100000001110' '1100000001110' '1100000001110'};
C = cellfun(@(a,b) char((a ~= b) + '0'), A, B, 'UniformOutput', false)
However, I don't really see a reason to operate on strings, when operating on numbers (and keeping it that way) would be much faster:
A = reshape(bin2dec(A), size(A))
B = reshape(bin2dec(B), size(B))
C = bitxor(A, B)

thank u sir....will try the second method for sure
Sir i have a problem in executing the second command, it says 'Undefined function or method 'bitxor' for input arguments of type'cell'. What should i do?

Hum, are you sure you've run the first two lines (i.e. converted your cell arrays of strings into matrices of numbers)? By the 3rd line, A and B shouldn't be cell anymore.
setxor can be used, like c=setxor(A,B)
