I have this matrix:
1 2 3 4 5 6 7 8 5 5
3 3 3 3 3 4 4 4 5 5
1 4 3 4 3 4 4 4 5 5
3 3 3 3 4 4 4 5 5 5
And I want this as the result:
1 2 3 4 5 6 7 8 5 5 0 0 0
0 3 3 3 3 3 4 4 4 5 5 0 0
0 0 1 4 3 4 3 4 4 4 5 5 0
0 0 0 3 3 3 3 4 4 4 5 5 5
How can I do this as a script?
Please help
Thank you

B=[1 2 3 4 5 6 7 8 5 5
3 3 3 3 3 4 4 4 5 5
1 4 3 4 3 4 4 4 5 5
3 3 3 3 4 4 4 5 5 5];
[m,n]=size(B);
result=spdiags(B,0:n-1,m,n+m-1);
full(result)
