Q2: If the matrix B is defined in MATLAB as following: 2 -1 5 3 7 10 4 9 B = -3 7 8 5 1 4 6 12 Choose the correct MATLAB code to Calculate the following: Average Identity matrix eye(4)/B sum(sum(B))/16 inv(B)*B Inverse Sum

The following is a Matlab code. I am getting too big of an error. The max error should be less than 1*10^-3. I think its because of the backslash operator I used here, X = A \ b. I can't do X = A * inv(b) because b is not a square matrix. How should I reduce the error? % Problem 1% Step 1: Compute the right-hand side vector bn = 20;Xo = ones(n, 1); % Column vector with ones in each componentA = zeros(n); % Initialize the matrix A for i = 1:n   for j = 1:n       A(i, j) = 1 / (i + j - 1);   endend b = A * Xo; % Step 2: Solve the system AX = b numericallyX = A \ b; % Backslash operator for numerical solution % Step 3: Compute the error vector E and find the maximum componentE = X - Xo;E_inf = max(abs(E));
