Verify if an NxN matrix is a Pandiagonal Prime Magic Square.
Required properties:
1) N^2 prime values ( No repeats, 1 is a non-prime ) 2) Every row, column, diagonal, anti-diagonal, broken diagonals sum to same value 3) Magic Constant is the sum of a row/column/diagonal
Input: M (Matrix NxN)
Output: Magic Constant ( 0 if invalid )
Example:
m=[7 107 23 103;89 37 73 41;97 17 113 13;47 79 31 83]; Magic is 240
Rows;Columns; Diags 7+37+113+83, 107+73+13+47, 23+41+97+79, 103+89+17+31;
Anti-Diag 103+73+17+47, 23+37+97+83, 107+89+13+31, 7+41+113+79
