Problem #2 Part 1 The relationship between the imput of a system x, and its output, y, is assumed to be given by Assume that p experimental data pairs (xi, yi. i-1,2,..p were obtained and saved in a MATLAB mat file named expdata.mat. Write a MATLAB script that calculates the optimal values of the relationship parameters c, and c2 in the least-squares sense. Your scrpt must also calculate the coefficient of determination R2. There is no requirement to generate any type of plots for this problem Part 2: Clearly explain in your own words the following statement: The model param are caleulated using the least-squares method
