When I try to call block analogread, everytime I build will pop:
The corresponding 'msfun_arduino_analogread.tlc' file for the MATLAB S-function 'msfun_arduino_analogread' in block 'test1/Arduino Analog Read' must be located in the current working directory, the MATLAB S-function directory 'C:\Users\Julio\Documents\MATLAB\ArduinoIO\simulink', or the directory 'C:\Users\Julio\Documents\MATLAB\ArduinoIO\simulink\tlc_c'
and I ingnore it matlab just quit. Even the demo cannot work. Anyone has ideas?
Thanks, very helpful.
Why do we need to use fftshift twice?
How about power measurement? What is the correct way plot the power of the signal after using this algorithm. I'm using modulated periodic signal.
its very good - explains finally why we need fftshift twice. However, it should be stressed that the method works only for data of even size. For odd size data, the amplitude is correct but spectral phase will be wrong.
