% @deftypefn {Function File} @var{rval}= {} combs(@var{sym_set},@var{k})
% Function generates the nchoosek(N,K) combinations, and returns it.
% compute the combinations nchoosek(length(@var{sym_set}), @var{k})
% nchoosek is a much faster variant of this function.
% @example
% @group
%
% combs([1,2,3],2)
% %%returns value [1 2; 1 3; 2 3]
%
% combs(['a','e','i','o','u'],2)
% %%returns value [['a', 'e']; ['a', 'i']; ['a','o']; ['a','u']; ['e', 'i'];
% %%['e','o']; ['e','u']; ['i','o']; ['i','u']; ['o', 'u'];]
