Problem 3 (10 points) Develop a Matlab function myLinReg that finds the linear function f(x) -ao + ayr that best fits given data points (zi, y) using linear least squares regression. The input arguments to the function must be the two vectors x and y that contain the values of the data points. The output of the function shall be a two-element vector a that contains the values of ao and a and the error of the fit E defined as the sum of the squares of the residuals. Use problem 1 to help you debug your function
