Description: 脑波FFT变换
调用格式见m文件头部说明（下边也复制了一份）
有配套.DLL.h.lib.ctf文件，可以在C或C++环境中调用
------------------------------------
保存为FFT.m文件
输入参数： N：进行FFT变换的点数（要求是2的N次幂）；
fs：信号的采样频率（frequency of simpling）
sig：进行FFT变换的数组（一维）。
输出参数： f_sig:变换后的信号（一维数组）
E_delta、E_theta 、E_alpha、E_beta分别表示δθαβ相应频段的能量加和。
other为其余频段的能量加和（供参考用）

Description: 可以用FFT频谱对脑电信号进行提取。我们可以利用提取出的各个波段脑电信号，来诊断一些脑部疾病或者对大脑组织的电活动及大脑的功能状态进行分析。
1.将实验测得的脑电数据文件转换为文本文件(已经过50Hz陷波)， 获得在Matlab 平台上可直接使用的脑电信号数据，即0661.txt。
2.在Matlab中导入数据，并提取Fp1通道的脑电信号，通过FFT变换对α，β，θ，δ波段进行提取，并做FFT逆变换变到时域。
3.计算各个波段的功率谱。-FFT spectrum can be extracted on EEG. We can use the extracted EEG each band to diagnose some brain disorders or brain tissue on the brain' s electrical activity and functional status were analyzed. One would experimentally measured EEG data file into a text file (has been 50Hz notch), obtained in Matlab platform can be used directly EEG data, that 0661.txt. (2) import data in Matlab and extract Fp1 channel EEG by FFT transform α, β, θ, δ bands were extracted, and do FFT inverse transform variable to the time domain. 3 calculate the power spectrum of each band.
