本书对matlab由简单到难的介绍，尤其是在矩阵那一节，对很多细节处，一些平常书都不回介绍到的命令进行了详细介绍( the book introduce matlab from easy to hard，especially in introducing matrix，it tell many details which other book don‘t introduce)

本matlab编程小例子是用于找油气的物探领域中的信号频谱分析，实用性强，资料最后附有可供学习的网站，希望本资料有用。(This is a small example of matlab programming used to find oil and gas geophysical field in the signal spectrum analysis, practical, with final data for learning website and hope this information useful.)

用 LDPC 解码法，对原始信号通道的噪声进行评估，消去。具体原理可参照IEEE TCOM的论文。(Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our published journal papers with some additional improvements. In this code, we removed the parameter lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM. )
