One thing is to remember that we have to convert that matrix into a magical square at a minimal cost. function [magicMatrix] = magicSquare (n) %Function that iterates through a matrix of dimension n x n. % to create a magic square, where n must be an odd number. Furthermore, the sum of each row, column and diagonal must be the same. Location of value 1 is = ( 3 2 ,3-1) = (1,2) = 1 2 . In recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. squares generated, and it can also print the squares in table format (4), but Whenever the loop counter is divisible by n . Let's start with a 3 x 3 square: * Start with 1 in the top center box * Move diagonally up one row and right one column and fill in 2. If N is the order, then N x N different numbers are used to . A magic square is an grid of numbers in which the entries in each row, column and main diagonal sum to the same number (equal to ). Let the size of the magic square we will implement be n. Then, the first value (i.e., 1) is stored at position (n/2,n-1) in the magic square. import string def make_magic_square (n): if n < 1 or n == 2: return False if n % 2 == 1: return make_odd_magic_square (n) else: if n % 4 == 0 . A magic square is a matrix of I remember learning as a child how to construct a magic . Insert into the current grid position; Step 3. corners top-left, top-right and bottom-left of the 3x3 central square (this #include
