MATLAB: Stuck in Indexing of a Matrix(or Cell Array)

for loopmatrix arraymatrix manipulation

Hi all,I have just started learning MATLAB . Please find my codes below
m= ['A','B','C'];
cs=size(m,2);
for i=1:cs
  for j=1:cs
            if i~=j
           s1=(m(i));s2=',';s3=(m(j));
                 s=strcat(s1,s2,s3);
                      disp(s);
      end    
    end
  end
It produces the following output on command window.
* A,B
* A,C
* B,A
* B,C
* C,A
* C,B
But , i want to wrap up all the outputs into a single matrix (or Cell Array ) , Lets say new_M . So that the values of new_M shall contain all the above values like this .
new_M (6,1) =
[ A,B 
A,C
B,A
B,C
C,A
C,B ]
Your help will be highly appreciatated . Thanks in advance.

E.g., using the cell array approach:
m= ['A','B','C'];
cs=size(m,2);
new_M = cell(cs*(cs-1),1); % Pre-allocate your cell array
k = 0; % Initialize counter for cell array
for i=1:cs
    for j=1:cs
        if i~=j
            s1=(m(i));s2=',';s3=(m(j));
            s=strcat(s1,s2,s3);
            disp(s);
            k = k + 1; % Increment cell array counter
            new_M(k) = {s}; % Stuff string into cell array element
        end    
    end
end
