This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to "capacity_plot_main.m". The latter file deals with all the other capacity plots given in the book in Chapter 2. All programs are verified with MATLAB versions 6.0 and above with signal processing and communications toolboxes.(This chapter contains sample programs for determining capacity.
