function P = myperms(v)
% simple recursive scheme to generate all permutations of a vector v.
n = numel(v);
if n <= 1
  P = v;
else
  P = zeros(factorial(n),n);
  f = factorial(n-1);
  L = 1:f;
  for ii = n:-1:1
    P(L,1) = v(ii);
    P(L,2:n) = myperms(v(setdiff(1:n,ii)));
    L = L + f;
  end
end

Hi, this is the code I have for calculating a permutation of a double array. I am just wondering how could I turn the output to be a cell array. I tried to use "num2cell" but it failed. Thanks!
