How to shift the element in diagonal matrix

As question mentioned, I created a matrix

v = [4 5 6 7]

diag(v)

then, I would like to have a matrix as [0 4 0 0; 0 0 5 0; 0 0 0 6; 7 0 0 0] also [0 0 0 4; 5 0 0 0; 0 6 0 0; 0 0 7 0] by using the command diag, is there any way to do?

Thank you !

 >>circshift(diag(v),1,2)

     0     4     0     0
     0     0     5     0
     0     0     0     6
     7     0     0     0

 >>circshift(diag(v),-1,2)

     0     0     0     4
     5     0     0     0
     0     6     0     0
     0     0     7     0
