Matrix A is a tridiagonal matrix of dimension (m x m). The upper diagonal is denoted as upperd, the main diagonal is denoted as maind and the lower diagonal is denoted as lowerd.
Vector q is of dimension (m x 1).
Write a psuedocode and MATLAB code for a for-loop that computes the matrix-vector product w = Aq using the diagonals upperd, maind, and lowerd.
How many flops are required to compute w = Aq?
