How can I generate this tyope of matrix as shows in the follow

I don't even know how to describe this matrix but it follows some rules. How can I generate a N*N matrix like follows. This is an example when N=8 and N=10. N is the only variable. Can anyone help me to generate matrix like follows when the value of N is given ? This is when=9 A =

     0     1     1     0     1     1     0     1
     1     0     1     1     0     1     1     0
     1     1     0     1     1     0     1     1
     0     1     1     0     1     1     0     1
     1     0     1     1     0     1     1     0
     1     1     0     1     1     0     1     1
     0     1     1     0     1     1     0     1
     1     0     1     1     0     1     1     0

When N=7

A =

     0     1     1     0     1     1     1
     1     0     1     1     0     1     1
     1     1     0     1     1     0     0
     0     1     1     0     1     1     1
     1     0     1     1     0     1     1
     1     1     0     1     1     0     1
     1     1     1     0     1     1     0

Hi Yishun Wang, I think in N=10 it follows some rules, but in N=7 no rule here.

[Said BOUREZG]

can you give us an other matrix to see the rules exactly

This attached function can help you, b = spematrix(9)

b =

     0     1     1     0     1     1     0     1     1
     1     0     1     1     0     1     1     0     1
     1     1     0     1     1     0     1     1     0
     0     1     1     0     1     1     0     1     1
     1     0     1     1     0     1     1     0     1
     1     1     0     1     1     0     1     1     0
     0     1     1     0     1     1     0     1     1
     1     0     1     1     0     1     1     0     1
     1     1     0     1     1     0     1     1     0

Matlab's 'toeplitz' function can simplify this generation greatly.
