Returns broken diagonals of a magic square
diag.off(a, offset = 0, nw.se = TRUE)
a |
Square matrix |
offset |
vertical offset |
nw.se |
Boolean variable with TRUE meaning trace diagonals
along the northwest-southeast direction (point [1,n]
to [n,1]). |
Useful when testing for panmagic squares. The first element is always
the unbroken one (ie [1,1] to [n,n] if nw.se is
TRUE and [1,n] to [n,1] if nw.se is
FALSE.
