Magic Square

Description

Create a magic square.

Usage

magic(n)

Arguments

n	numeric scalar specifying dimensions for the result; n must be a scalar greater than or equal to 3.

Details

A magic square is a square matrix where all row and column sums and also the diagonal sums all have the same value.

This value or the characteristic sum for a magic square of order n is sum(1:n^2)/n.

Value

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

Note

A magic square, scaled by its magic sum, is doubly stochastic.
