Hello everyone, I have got two matrices(path & path1) and want to put these two together in a way that I get path 3
path =
Columns 1 through 13
14 9 5 2 1 0 0 0 0 0 0 0 0
path1 :
1 2 5 9 14 0 0 0 0 0 0 0 0
1 2 5 9 15 0 0 0 0 0 0 0 0
1 2 5 10 16 0 0 0 0 0 0 0 0
1 3 7 11 17 0 0 0 0 0 0 0 0
1 3 7 12 18 0 0 0 0 0 0 0 0
1 4 8 13 19 0 0 0 0 0 0 0 0
Columns 14 through 19
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
Path 3:
14 9 5 2 1 2 5 9 14 0 0 0 0
14 9 5 2 1 2 5 9 15 0 0 0 0
14 9 5 2 1 2 5 10 16 0 0 0 0
14 9 5 2 1 3 7 11 17 0 0 0 0
14 9 5 2 1 13 7 12 18 0 0 0 0
14 9 5 2 1 4 8 13 19 0 0 0 0
Columns 14 through 19

If I understand correctly what you want to do, this will work:
path = path(path>0);
path3 = circshift(path1, [0 size(path,2)-1]);
path3(:,5) = 0;
pathm = [repmat(path, size(path1,1), 1)...
zeros(size(path1,1),size(path1,2)-size(path,2))];
path3 = path3 + pathm
( EDIT: slight reformat to add ‘...’ to make it fit in the window without ambiguity. )

This sounds like graph theory, which unfortunately is not an area of my expertise. I will do what I can to help with the MATLAB code, but cannot promise help on the underlying concepts.
