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.

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.
