Let now n denote the number of subintervals into which discretization points x1, x2, etc. divide the interval [0, L]. Set up and solve a linear system (5) for the case n = 20 using MATLAB (see Appendix B after these Instructions). Use the values L = 100 ft, H = 12 ft, T = 3000 lb, and W(x) = ( 6 lb/ft (iced cable), 0 x L/2 ft 3 lb/ft (clean cable), L/2 < x L ft. Write the numerical values of your solution at several locations along the cable, as requested in the Answer Sheet. Round these values to 4 decimal places. Also, use Matlab to plot the graph y = y(x) which you obtained on the interval 0 x L (i.e., include the end points). Label the axes. For example, to label the x-axis, type: xlabel(whatever you want to use for the x-label,fontsize,12). Print your computer output, including the plot of y(x), and staple it to the Answer Sheet
