Ouputting all the permutations with repeated symbols in MATLAB

Hi, so I have a problem that's very similar to the classic "Mississippi" permutations problem. That is, "How many different linear arrangements of the letters from the word, 'Mississippi' are there?" I know how to do the actual calculation to find this, you would just do the 11!/(2!*4!*4!*1!) = 34,650. My question is, is there a way where you could have MATLAB generate all of these 34,650 possible arrangements, not just calculate the number 34,650?

Read about perms. After this, you can try unique and get the required output.

str = 'Mississippi' ; 
S = perms(str) ; 
iwant = unique(S,'rows') ;   % output would be exactly 34650

Thank you KSSV, this was very helpful. One more thing, if I wanted to apply this same concept to a lengthy number string, (Ex: [1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0]) how would I do this? I tried perms, but the length of that vector exceeds the limit for the input you can do. I'm really just interested in seeing all the ways you could arrange the nonzero values in the vector.

This is a huge input to achive the same.....
