Problem 10 points (MATLAB code submission is required) A set of 7 data points are given below: Notice that the y-values for the first point and the last point are identical. (a) Write a MATLAB code to use Program 7-1 from the textbook to compute the Discrete Fourier Transform (DFT) for the function y(t). * Please note (i) Example 7-3 contains an error when calling the program 7-1: It should be DFT(t,y), not DFT (y,t) (on page 268). This has been discussed in this week's recitation. (ii) In Program 7-1, the array f has a length of " 2N ", not " 2N+1 ", as it has used the fact that f(1)=f(2N+1) when storing the value for f. (b) Make a table for the coefficients Ak,Bk (frequency domain analysis). Is there a dominant frequency
