Hello, Greetings! I have two values (suppose 1 and 2). How can I form all the possible combinations of 3*3 matrices from these two values. For example all the possible combinations of 2*2 matices from 1 and 2 are [1 2; 1 2]; [1 2; 2 1]; [1 1; 2 2]; [2 1; 2 1]; [1 1; 1 2]; [1 1; 2 1] etc...

function list = SetPartition(n, k)
% Purpose: Set partitioning
% LIST = SetPartition(N)
% N is an integer
% Return the cell list of all partitions of the integer set {1:N}.
% Output LIST is the cell of size (B x 1), where B is Bell number B(n),
% the number of ways of partitionning. Each list{j} is a partition of the
% set {1:N}.
%
% LIST = SetPartition(N, K)
% N and K are integers. Specify the fixed size K of the partitions.
% Return the cell list of all partitions of the integer set {1:N} in K
% non-empty subsets.
% Output LIST is the cell of size (S x 1), where S Stirling number of the
% second kind S(n,k). Each list{j} is a partition of {1:N} having
% exactly K non-empty subsets.
% LIST is large for N large (of course) and K ~ N/2
%
% User can provide a set with elements different than {1:N} by substitute
% the first input argument (N) with SetElements
% >> LIST = SetPartition(SetElements, ...)
% where SetElements is an array or cell array of N elements.
%
% USAGE EXAMPLE 1:
%
% % Find all the length-2 partitions of {1,2,3,4}
% p=SetPartition(4,2);
% % Display
% fprintf('All the length-2 partitions of {1,2,3,4} are:\n')
% for i=1:size(p,1)
% fprintf('\t')
% for j=1:length(p{i})
% s = sprintf('%d,', p{i}{j});
% s(end)=[];
% s = sprintf('{%s}', s);
% if j<length(p{i})
% s = sprintf('%s + ', s);
% end
% fprintf('%s', s)
% end
% fprintf('\n')
% end
%
% EXAMPLE 2:
% p=SetPartition({'mouse' 'dog' 'cat'});
%
% Notes:
% - The result has the same class as N.
% - The result size growth very steep with respect to N. It advisable to
% call PARTITION with N <= 11.
% - Recursive algorithm in a general case (i.e. when only N is provided)
% Iteration (derecursive loops) when K is specified.
