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
