dit_fft
本程序包括:DFT(离散傅里叶变换),FFT(快速傅里叶变换),IFFT(快速傅里叶逆变换),conv(卷积:圆周卷积、线性卷积),主要应用于信号处理,既可以对实序列做上述操作,也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)
