Matlab程序，GUI窗口 用FFT程序计算有限长度正弦信号y=sin(2*pi*f*t) ,0<=t<=N*T-FFT program calculate the finite length of the sinusoidal signal y = sin (2* pi* f* t), 0 < = t < = N* T respectively the DFT results obtained and analyzed and discussed in the fol

关于FFT的matlab，运用一些特定函数方程，设定wn的值进行编写matlab文件(Write a Matlab function fastft.m which implements the Fast Fourier Transform (FFT) algorithm for computing the DFT.)
