代码说明：

特征分解型求取离散分数阶傅里叶变换特征分解算法通过求ＤＦＴ的核矩阵Ｆ（ｋ，ｎ）的特征值和特征向量构造ＤＦＴ核矩阵的分数幂，以此作为Ｆａ（ｋ，ｎ）来计算ＤＦｒＦＴ。(The kernel matrix eigenvalue decomposition algorithm for DFT F (k, n) characteristic value And the feature vectors are constructed as the fractional powers of the DFT kernel matrix, which are used as Fa (k, n) To calculate DFrFT.)

matlab需要那么复杂的多重积分,实在没办法才考虑使用.一般来说,积分中带有参数,无论是被积表达式或者说积分限都是相当麻烦的,求解消耗的时间非常多.............数值积分才是解决问题的通法,可以自己调节精度~(it is good. If you visited Indianapolis you would be able to find your way around easily because most of the streets corss each other like a chessboard(棋盘). In the center of the city, called the Circle, stands the Soldiers and Sailors’Monument, 100 Meters high. Also in the center there are many buildings made of the famous Indiana stone, which makes them white in color.)

wavle-conoising
将信号映射到小波域，根据噪声和噪声的小波系数在不同尺度上具有不同的性质和机理，对含噪信号的小波系数进行处理。实质是减少剔除噪声产生的小波系数，最大限度的保留真实信号的系数。 (Will be mapped to the signal wavelet domain, according to noise and noise of wavelet coefficients in different scales with different properties and mechanism of signal with noise of wavelet coefficients for processing.Essence is to reduce the noise out of wavelet coefficients, the maximum keep the coefficient of true signals. )
