music 算法解决问题续,欠估计情况下的精度(music algorithm to solve the problem continued, underdevelopment of the estimated accuracy)

代码实现了基于卡尔曼滤波算法的信号估计，该算法有很好的跟踪能力，能用于信道事变的情况(Code based on the Kalman filter algorithm estimates the signal, the algorithm has good tracking ability can be used in case of channel events)

this code can be use in prediction filter of seismic data.

This tutorial is designed to give the reader an understanding of Principal Components Analysis (PCA). PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Before getting to a description of PCA, this tutorial first introduces mathematical concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors and eigenvalues. This background knowledge is meant to make the PCA section very straightforward, but can be skipped if the concepts are already familiar.

there is code for sampling a signal and adding random noise in signal...
