A persymmetric matrix, also known as a symmetric Toeplitz matrix, is a special type of square matrix that exhibits symmetry in a specific manner. An \\( n \\times n \\) matrix \\( A \\) is defined as persymmetric if it satisfies the condition: \\\[ A\[i, j\] = A\[n-j+1, n-i+1\] \\\] for all valid indices \\( i \\) and \\( j \\).
