i need help with this matlab exercise. Thanks.

- Submit a one-page PDF report and Matlab scripts (as m-files) Part A: The following four methods are proposed to compute 191/3. Using Matlab, rank them in order, based on their apparent speed of convergence, assuming p0=2. Method 1: pn=1918pn1+19/pn12. Method 2: pn=pn13pn12pn1319. Method 3: pn=pn1pn1221pn1419pn1. Method 4: pn=(pn119)1/2 Continued on page 2. Part B: Present a table or a plot of the absolute error pnp against n to further illustrate the convergence or divergence of the iterations in Part A. Part C: Using your computed errors, estimate the order of convergence and the asymptotic error constant for each convergent iteration. Explain clearly how you compute each constant. A table or plot may be useful here as well. There are several possible ways to compute the constants. Some methods are better than others
