Next, you will write a function to perform the DTFT: function % DTFT % y = dtft(x, w) Evaluate the DTFT of Matlab sequence object, x, at radial frequencies given by double array w. Return a double array, y. For example, start with our old friend, sequence x[n] = [n] [n] [n 1]: >> x = sequence([1 1 1], -1); Make an array of frequency from -to . This is most easily done using Matlab's linspace command. Choose an odd
