MATLAB: How to join two matrices ?

combination of matrices

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

Best Answer

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. )
