I'm trying to generate a list of unique 2 digit number combinations from 0 to 9 without repetition. Using npermutek:
a = npermutek(0:9,2)% OUTPUT:
% a =
%
% 0 0
% 0 1
% 0 2
% 0 3
% 0 4
% 0 5
% 0 6
% 0 7
% 0 8
% 0 9
% 1 0 <-- Repetitive
% 1 1
% 1 2
% 1 3
% 1 4
% 1 5
% 1 6
% 1 7
% 1 8
% 1 9
% 2 0
% 2 1 <-- Repetitive
% ... ...
% 9 9
However I want to filter out the repetitive number combinations like e.g. 10 and 21, since they fall into the same category as 01 and 12 respectively. nchoosek(0:9,2) does not suit my needs as numbers like 00, 11 … are not represented.
