As I understand from your question, you want to build a character array of all those letters that appear multiple times in a word. For example if your word is 'mississippi', the character array should contain 'isp'.
The code for the above logic is
v = 'mississippi';
u = unique(v);
m = [];
for i = 1:length(u)
if(length(strfind(v,u(i)))>1)
disp(u(i))
m = [m,u(i)]
end
end
disp(m)
