The relationship between the input of a system, x, and its output, y, is assumed to be given by: 1 In x + x y(x) = 1 C 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 and c in the least-squares sense. Your script must also calculate the coefficient of determination R2. Note: There is no requirement to generate any type of plots for this problem.
