Fast Fourier transform - MATLAB fft - MathWorks - MATLAB and Simulink for Technical Computing - A哎,,肚子上的肉啊,愁得很。。 This MATLAB function returns the discrete Fourier transform (DFT) of vector x, computed with a fast Fourier transform (FFT) algorithm. ... The FFT functions (fft, fft2, fftn, ifft, ifft2, ifftn) are based on a library called FFTW [3],[4]. To compute an N-...

Fourier Transform (matlab)?有多2逼的主人就有多2逼的狗.。   >> clear >> t=[-2:0.01:2]; >> g=sqrt((t.^2)-4); >> plot(t,imag(g), 'r'); >> hold on >> plot(t,imag(fft(g)), 'b'); Not sure exactly what your problem is asking, but this might do it. I just use the built-in Fourier transform of Matlab. I assume you don't h...
