FFT - Fast Fourier transform Syntax Y = fft(x) Y = fft(X,n) Y = fft(X,[],dim) Y = fft(X,n,dim) Definitions The functions Y=fft(x) and y=ifft(X) implement the transform and inverse transform pair given for ve
i want to apply fft to the clutter signal with sampling frequency 5000 Hz.댓글 수: 1 Walter Roberson 2012년 11월 19일 What is a "clutter signal" ? Do you need to write the fft routine yourself, or can you use fft() ? 댓글을 달려면 로그인하십시...

Y =fft(X,n,dim) 说明 示例 Y=fft(X)用快速傅里叶变换 (FFT) 算法计算X的离散傅里叶变换(DFT)。 如果X是向量,则fft(X)返回该向量的傅里叶变换。 如果X是矩阵,则fft(X)将X的各列视为向量,并返回每列的傅里叶变换。 如果X是一个多维数组,则fft(X)将沿大小不等于 1 的第一个数组维度的值视为...
