Unformatted text preview: these methods. 3/. Find, by hand, the first order polynomial that best fits these four points and the resulting correlation coefficient. x: 1 3 6 10 y: 0 54 97 190 Check your answer by using "polyfit" and correlate. 4/. Use Matlab to fit a cubic polynomial to the following data: x 3 4 5 7 8 9 10 11 y 1.6 3.6 4.4 3.4 2.2 2.8 3.8 4.6 Plot the polynomial for x = 2 to 12 along with the data points and calculate the correlation coefficient. The cubic should have a maximum between x = 3 and x = 8. Locate this maximum twice, once using fzero and once using fminbnd , and output the maximum value of the cubic. Submit a script file (lab9.m) that does all this as proof of your attendance in the lab....
