Need design fourier series at least 4 inputs. on simulink matlab ( read scope of work in description)

[login to view URL] and create a series of fourier series demonstration with microcontroller. Microcontroller and Matlab programmable with at least 4 inputs. 2. Each channel can generate both Sine and Cosine signals with frequencies in the range of 1 kHz to 10 kHz and with a voltage of 0 - 5 v. 3. Demos can display Real-time Fourier series through the computer. With matlab program Comment This part only for design simulation by show status on scope on Simulink Propose of this design I will apply for Arduino board ,after test on Simulink finish Problem of my design , I think not correct and signal at scope not stable. My design is both file , design in matlab 2015 , I would like design matlab 2016b
