Constructing a magic square

 

Three by three magic square: Each square has a number from 1, 2, ..., 9 used once. Sum along any row, any column, and diagonal are all 15. What are the numbers in each square?

                                                                        1 + 2 + ... + 9 = 45

Write the square as 3 by 3 matrix.
