本文从matlab的基本知识入手，本书侧重于利用大量的实例来引导读者快速掌握matlab的各种功能。(In this paper, the basic knowledge to start matlab, the book focuses on the use of a large number of examples to guide readers to quickly grasp the various features of matlab.)

Compressive Sampling是最近讨论非常热烈的数据处理方法。用一个与变换基不相关的观测矩阵将变换所得到的高维信号投影到一个低维空间上，然后通过优化求解从这些少量的投影中以高概率重构出原信号。(Compressive Sampling is a very lively discussion of recent data processing method. A base with the transformation matrix will not change the relevant observation obtained a high-dimensional signal projected onto low-dimensional space, and then solved by optimizing the projection from these small reconstructed with high probability in the original signal.)

采用极大值法实现图像处理中的小波去模糊。基于matlab函数实现。(Using the maximum value method to achieve image processing wavelet deblurring. Based on matlab function implementation.)

瞬变电磁法的matlab一维正演分析，采用的是磁偶极子激发的瞬变电磁场(matlab transient electromagnetic method of one-dimensional forward analysis, using the magnetic dipole excitation transient electromagnetic field)

MATLAB中用m文件实现卡尔曼滤波算法(M file implementation using MATLAB Kalman filter algorithm)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )
