You are required to design, code, and test a Matlab program that performs the followings:
  1. Request the user to enter a single variable function to find root, upon which a graph should get displayed.
  2. Request the user to enter the interval that contains roots by looking at graph.
  3. On the same window, the user should choose between‘Newton’ and ‘Newton raphson’ methods for a solution
  4. Display answer from the method and compare with fzero in same window.
How to do this? What does this question wants? Anyone can explain in more details, including the codes as well.

ezplot is an older routine. It can plot functions of one variable and functions of two variables.
fplot() is a newer routine. It can plot functions of one variable, and it can plot parametric surfaces defined by separable functions for x and y, but it cannot plot functions of two variables. fplot() has a lot of hidden work inside to detect discontinuities and to try to figure out how close together it needs to sample the function to get a reasonably smooth output.
ezplot() plots the function and then returns. fplot() sets up some conditions and then returns, leaving a separate thread running doing the calculations. If you zoom into something done by ezplot() then it just enlarges what was already calculated; if you zoom into something done by fplot() then it will go back through the internal routines for detecting discontinuities and generating smooth lines.
