numeric scalar specifying dimensions for the result

Value

Returns an n-by-n matrix constructed from
the integers 1 through $N^2$ with equal row and column sums.

Details

The value of the characteristic sum for a magic square of order n is
$sum(1:n^2)/n$. The order n must be a scalar greater than or
equal to 3; otherwise, the result will be either a nonmagic square, or
else the degenerate magic squares 1 and [].
