I'm trying to make a banded matrix in MATLAB like the one in my picture.

I'm trying to use the spdiags function but I'm not going even close to getting the same matrix.

I have tried the help in Matlab but have had no luck yet.

How can you tell the bandwidth is 7?

Can you explain in more details what you have tried?

And the bandwith here is 5.
