Using Matlab:

Create the following vectors: x = (1.5 -2.3 5 -4 7 -1 3 0.8 -2 4.2 1.3 1.4 0 0.9 1.7 -4) y = (-0.1 1.2 3.4 -4 3 -1.5 3.3 5.2 0.7 7 -3 9 4 8 2 7) Using Least-Squares method find a line, a parabola, and a cubic parabola which provide the best fit to the given points. Plot the points and graphs in the same figure. Using Least-Squares method find a graph of a polynomial of order 10 which provides the best fit to the given points. Plot the points and the graph in the same figure. Compare and analyze your numerical results. Create two random vectors x and y of the length 200
