中文说明： 分数阶傅里叶变换计算方面,包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，包括调制，解调，信噪比计算，有借鉴意义哦，计算两个矩阵之间的欧氏距离，ML法能够很好的估计信号的信噪比。
English Description：
Calculation of fractional Fourier transform, include MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, including modulation, demodulation and signal to noise ratio calculation, reference, compute the Euclidean distance between two matrices, ML method can be a good estimation of the signal to noise ratio.
