MATLAB: How to concatenate each row of a matrix into a vector

concatenateMATLABmatrixnumber to stringrowvector

Hey there,
I have a matrix 1000×7 of double (only 0 and 1) like that :
0     0     1     1     0     0     0
0     0     1     1     0     0     0
1     0     1     1     0     0     0
...
0     0     1     1     0     0     0
0     0     1     1     0     0     1
0     0     1     0     0     0     0
For each row, I have to concatenate each column value to get a vector of strings like this
0011000
0011000
1011000
...
0011000
0011001
0010000
Do you have any idea of how could I do that ?

% create fake data
A = [0     0     1     1     0     0     0
0     0     1     1     0     0     1
0     0     1     0     0     0     0]; 
% Convert to char array
s = arrayfun(@(x)sprintf('%d',x), A)
% s =
%   3×7 char array
%     '0011000'
%     '0011001'
%     '0010000'
% if desired, convert to cell array of strings
c = cellstr(s)
% c =
%   3×1 cell array
%     {'0011000'}
%     {'0011001'}
%     {'0010000'}
