matlab编写的离散fourier变换程序，好东西哦　

A implementation of the discrete Fourier transform in visual basic classic.

FFTGUI Demonstration of Finite Fourier Transform. 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 Explo ...

shape based image retrieval using fourier description

This file is a function under matlab which allow to compute and plot fast fourier transform of a signal. We can observe the effect of the signal parameter can be changed such as frequency and N points.

Getting to Know the FFT What is the FFT? FFT = Fast Fourier Transform. The FFT is a faster version of the Discrete Fourier Transform (DFT). The FFT utilizes some clever algorithms to do the same thing as the DTF, but in much less time.
