Let F = 1 0 -1 4 4 -7 3 -1 (a) Are FFT and FTF defined? Yes, both FFT and FTF are defined. FFT is defined and FTF is not defined. FFT is not defined and FTF is defined. No, both FFT and FTF are not defined. (b) What size is each product? (If the matrix is undefined, enter DNE into both answer blanks.) FFT is X and FTF is (c) Can FFT = FTF? Explain. Yes, because FFT and FTF have the same dimensions. No, because FFT is not defined and FTF is defined.
