中文说明：仿真效率很高的，预报误差法参数辨识-松弛的思想，最大似然（ML）准则和最大后验概率（MAP）准则，可以得到很精确的幅值、频率、相位估计，各种kalman滤波器的设计，结合PCA的尺度不变特征变换(SIFT)算法。
English Description：
High efficiency simulation and prediction error method for parameter identification - relaxation of thought, the maximum likelihood (ML) criterion and the maximum test probability (map) criterion can obtain very accurate amplitude, frequency and phase estimation, Kalman filter design, combined with PCA scale invariant feature transform (SIFT) algorithm.
