Hello,

Suppose I have a vector of N elements, and I need to find all possible permutations {N \choose n} for n=1,2, ..., N. How can I do that?

Example: Suppose I have the vector [1 2 3], then all possible permutations are: 123 (n=3), 12, 13, 23, (n=2), 1, 2, 3 (n=1)

Thanks

I did not know it is built-in in MATLAB. Thanks

It is not working. I do not know why. I think choosek does the job. Thanks anyway
