This program will store roster and rating information for a soccer team. coaches rate players during tryouts to ensure a balanced team. (1) prompt the user to input five pairs of numbers: a player's jersey number (0 - 99) and the player's rating (1 - 9). store the jersey numbers in one int vector and the ratings in another int vector. output these vectors (i.e., output the roster). (3 pts) ex: enter player 1's jersey number: 84 enter player 1's rating: 7 enter player 2's jersey number: 23 enter player 2's rating: 4 enter player 3's jersey number: 4 enter player 3's rating: 5 enter player 4's jersey number: 30 enter player 4's rating: 2

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)
