7. (Matlab) Write a MATLAB user-defined uite a MATLAB user-defined function that determines the best fit of an exponential function of the form y = bemx to a given set of data points. Name the function [b m] =ExpoFit(x,y), where the input arguments x and y are vectors with the coordinates of the data points, and the output arguments b and m are the values of the coefficients. The function ExpoFit should use the approach that is described in the lecture note for determining the value of the coefficients. Use the function to solve Problem #2
