I have tried to use a quiver plot function but that has not really worked so well. I guess I just need help with the initial code to start for the first two questions, as I am not too advanced in Matlab

1. We do not know anything about the curve equation, as you did not post that, so we have difficulty offering you hints on implementation, or even what it means to simulate the evolution of the curve.
2. See tic() and toc() . If you suspect a polynomial cost, you can do a log fit to estimate the degree of the polynomial. Hint: if you only measure at 4 points, they are not expecting a polynomial of degree more than 3, so you could check the small degrees individually to determine how good the fit is.
