Webfunction fftgui(y) %*****80 % %% fftgui() Demonstration of Finite Fourier Transform. WebMay 23, 2016 · If you use numpy.fft.fft () (I guess scipy.fft () method is an alias for it), you can obtain frequencies of respective components with numpy.fft.fftfreq (). The first argument of numpy.fft.fftfreq (n, d=1.) is the number of samples, while the second ( d) is the sampling interval (1/f). You need to find an appropriate d. Share Improve this answer

Webfunction fftgui(y) % FFTGUI(y) plots real(y), imag(y), real(fft(y)) and imag(fft(y)). % FFTGUI, without any arguments, uses y = zeros(1,32). % When any point is moved with the mouse, the other plots respond. % Inspired by Java applet by Dave Hale, Stanford Exploration Project, % http://sepwww.stanford.edu/oldsep/hale/FftLab.html the vines craig nicholls

If y is a vector containing a few dozen elements, fftgui(y) produces four plots real(y) imag(y) real(fft(y)) imag(fft(y)) You can use the mouse to move any of the points in any of the plots, and the points in the other plots respond. WebNow close the fftgui gure window and enter the command fftgui at the Matlab prompt. The gure window will reappear with all plots initialized to y = zeros(32, 1).
