Question: Let A be an m m tridiagonal matrix. We will call the superdiagonal entries above the main diagonal the upper diagonal entries, and the subdiagonal

Let A be an m m tridiagonal matrix. We will call the superdiagonal entries above the main diagonal the upper diagonal entries, and the subdiagonal entries below the main diagonal the lower diagonal entries. For the MATLAB components of this problem, please include a listing of your code and a listing of the results from any tests you run. (a) Leveraging the tridiagonal structure of A, how many flops are required to compute w = Ab, where b Rm? Your answer should be written in terms of m. Show your work/reasoning
