The idea is to calculate sum of diagonals example [ [1,2,3], [4,5,6], [7,8,9] the correct answer would be [1,5,9] [3,5,7] = total 30. def sum_of_matrix (data): arr_solver = [] counter = 0 counter2 = -1 while ... Web24 Apr 2024 · Therefore we have P2 = H − C = P. So P is also a projection matrix. So hii = pii + cii = pii + 1 / n. Since projection matrices are always positive semidefinite, the diagonals of P satisfy pii ≥ 0. (In fact, you can show that since P is symmetric and idempotent, it satisfies 0 ≤ pii ≤ 1 .) Then hii ≥ 1 / n as needed.
