The magic square is an arrangement of numbers in a square grid in such a way that the sum of the numbers in each row, and in each column, and in each diagonal is the same. MATLAB has a built-in function magic (n) that returns an n x n magic square. In a script file create a (6 × 6) magic square, and then test the properties of the resulting matrix by finding the sum of the elements in each row, in each column and in both diagonals. In each case, use MATLAB's built-in function sum. (Other functions that can be useful are diag and fliplr.)
