Matrix G is as follows:
G = [
1 2 3 1 0
1 2 1 0 0
1 4 3 1 2
1 3 4 2 0
1 0 0 0 0
];
I want to produce 5 set of matrix. The first set include only first column. The second set include the second and first columns from matrix G. The 3rd set includes the third, second and first columns from matrix G. ...
OUT1 = [
1
1
1
1
1
];
OUT2 = [
2 1
2 1
4 1
3 1
];
OUT3 = [
3 2 1
1 2 1
3 4 1
4 3 1
];
OUT4 = [
1 3 2 1
1 3 4 1
2 4 3 1
];
OUT5 = [
2 1 3 4 1
];

G = [
1 2 3 1 0
1 2 1 0 0
1 4 3 1 2
1 3 4 2 0
1 0 0 0 0
];
ncols = size(G,2);
OUT = cell(ncols,1);
for nc = 1:ncols
OUT{nc} = fliplr(G(:,1:nc));
OUT{nc}(any(OUT{nc}==0,2),:) = [];
end
Note that I used a cell array, rather than variables names with embedded numbers, which are bad coding practice.
