Part(iii)
The file used to create the plots is "HW3_Script this file contains a series of for loops that take data from the root functions and places them into a "Table" from here it organizes the data and titles it. The convergence plot uses the information from the "Table" to plot the information on a a graph that is setup by calling the "setdefaults" function.
Part(ii)
