how can we do it for fractional order butterworth low pass filter ?????
@trs5127 Жыл бұрын
Order cannot be a fraction as far as I'm aware. You round it off to the next whole number

I have 15 years radiosonde Temperature data in excell. I made the program like this: 1. Temp=xlsread('Addis_Ababa_wholeRS.xlsx',4); % read the data 2. Height=Temp(:,1); % all row column one is height in Km 3. Temperature=Temp(:,2:end); % column 2 to end is Temperature in degree Centigrade 4. m=Temperature; 5. N=length(m); % lenght of the data 6. fs=1; % Sampling frequency 7. subplot(2,1,1) 8. plot(m) 9. title('\bf Temp Variation over Addis Ababa station during 2006 - 2020 at 2 (Km)') 10. ylabel('Amplitude') 11. xlabel('Month') 12. mf=fft(m); % Fast Fourier Transform which convert time signal into frequency Domain 13. Q=abs(mf); % Take the magnitude of the Fourier Transform 14. ps=abs(mf).^2; % Power Spectrum Density 15. fa=(0:N/2).*(fs/N); % Frequency Analyze 16. b=abs(mf(1:length(fa))); % Make the same dimension of frequency analysis with the time signal 17. c=abs(m(1:length(fa))); 18. subplot(2,1,2) 19. plot(fa,ps(1:length(fa))) 20. title('\bf Temp Peaks for Addis Ababa station during 2006 - 2020 at 2 (Km)') 21. ylabel('Power Spectrum') 22. xlabel('Frequency') My question raise here is how can I plot frequency vs Amplitude. In number 19 above I can plot(fa,ps(1:length(fa))) but my advisor wants to plot(fa, Amplitude). Please help me Thank you.

I have created the .exe file and is easily running in any PC that has already installed the Matlab Software For it to run in other PCs, it requires the Matlab Runtime (1,7 GB unzipped file from Mathworks), which is basically some Matlab Libraries Is there any way that the .exe file can run in any PC without the use of either Matlab Software or Matlab Runtime? Thanks for the Video and your time
