MATLAB: What is the function that the same as perms however can used n more than 10

MATLABmatrix

when i build a coding i used n less than 10, i used perms function.. then when get the correct coding the i test the coding in various size of n, which is n more than 10, however the length for perm is less than 10. what is the same function as perm, but can used for n more than 10?

Best Answer

I think you need to make your own function of perms, but one that only returns 1 of many permutations at a time. When you past n = 10, you'll run out of memory fast.
        3.5 GB   n = 11
       46.0 GB   n = 12
      647.6 GB   n = 13
     9764.0 GB   n = 14
One suggestion is to make a classdef object that track the ith permutation and will continuously return the the next permutation. But read this link as your attempt to compute permutations for n >> 11 gets fairly impossible...
