[Matlab] How to generate the shift identity matrix?

[davyzhu]

Hi all,

How to generate the shift identity matrix by its size and shift vaule?

For example,input size = 8, input shift value = 3
then, the matrix is
0 0 0 1 0 0 0 0
0 0 0 0 1 0 0 0
0 0 0 0 0 1 0 0
0 0 0 0 0 0 1 0
0 0 0 0 0 0 0 1
1 0 0 0 0 0 0 0
0 1 0 0 0 0 0 0
0 0 1 0 0 0 0 0

Any easy approach will be appreciated!
Best regards,
Davy

m( 1 , : ) = [0 0 0 1 0 0 0 0];
i = 1;
for i = 2 : 8;
m( i , : ) = circshift( m( i - 1 , : ), [1 1]);
end
