Problem 2 (5 points) Let n be a positive integer and let h be a small positive number. Let Dn be the square matrix of size n such that Dn;0,0 = h Dn:0,1 = h Dn;i,itl = 2h for i = 1, ..., n - 2 Dni+1,i = 2h for i = 0, ..., n - 3 Dn;n-1,n-2 h Dn;n-1,n-1 = 1 The subscripts D;i,j indicate the entry at row index i and column index j of the matrix Dn, For example, when n = 4 we have -2 2 0 DA = 2h 0 O 0 -2 Write a function called solve_D which takes input parameters n, h and b (a 2D NumPy array of size n by 1) and returns a solution of the system of equations ( Dn - In) x = b where In is the identity matrix of size n. The return value x is a 2D NumPy array of size n by 1. The NumPy function np. diag is helpful. In [ ] : # YOUR CODE HERE F11 40)) F12 44 F8 F9 F7 FZ F3 000 F4 F5 F6 % &
