That can be done in Python in one line,
def Siamese_magic_square(n):
return [[(i+j+(n+1)/2)%n*n+(i+2*j+1)%n+1 for j in range(n)]
for i in range(n)]
For example,
Siamese_magic_square(3)
[[8, 1, 6], [3, 5, 7], [4, 9, 2]]
Siamese_magic_square(5)
[[17, 24, 1, 8, 15], [23, 5, 7, 14, 16], [4, 6, 13, 20, 22], [10, 12, 19,
21, 3], [11, 18, 25, 2, 9]]
