Python Program:

Example:

n=int(input("Enter N of N X N magic matrix(must be odd number) :"))
if n%2!=0 :
  print("Sum of rows|columns|diagonals of ", n," x ",n," magic matrix :", int((n*(n*n+1))/2))
else :
  print("N must be an odd")

Output:

  Enter N of N X N magic matrix(must be odd number) : 5
  Sum of rows|columns|diagonals of 5 x 5 magic matrix : 65

Remember : Magic matrix are always odd value matrix

like : 3x3,5x5,7x7,.....

So, you must first check it for an Odd value

(n*(n*n+1))/2 #Formula to calculate the sum

To check for odd value

n%2!=0
