本文件夹中包含了多种回归算法，用matlab编写(This folder contains a variety of regression algorithm using matlab to prepare)

信号方面的一些程序集，如各种卷积，变换，频谱图等的程序，相信会对大家有所帮助~~(Some of the procedures set of signals, such as various convolution, transform, spectrum and other procedures, we believe it will help ~ ~)

快速浏览时间序列数据。而且可以直接创建时间序列的图示，非常方便快捷。(MAT2FIGURE allows you to review timeseries data contained in a matfile very fast and efficiently. Furthermore, the created figure file can be used to distribute these data. After opening a matfile, mat2figure scans (struct) arrays for vector signals, tries to determine the time signal (if not specified at commandline) and creates a figure with built-in signal browser. Among the features are: - At signal selector, each signal is marked, whether it s an ordinary signal, just has constant values or is monotonically in-/decreasing - Signals can be plotted into existing or new subplots, time axes are linked and subplots can be rearranged in up to 6 columns - snapshots of current plots can be created for switching between different views very fast - figure can be printed to clipboard, eps- or png-file with hidden menubar - timeseries data are stored within the figure-file and can be exported to matfile or to workspace - convenient handling via keyboard shortcuts - signal viewer)

THIS IS THE MATLAB SOURCE CODE

tridiagLU Obtain the LU factorization of a tridiagonal matrix

参数为：载波频率f0为20MHz，采样频率为4倍f0，脉宽为1us ，脉冲周期为20us 。其中：(Parameters: carrier frequency f0 is 20MHz, the sampling frequency is 4 times f0, a pulse width of 1us, the pulse period is 20us. Of which:)

水印的嵌入 检测 提取 该算法实现的功能比较容易看懂(watermark embeding extracting )

说明：  实现匹配滤波仿真的两个程序，每个程序生成四个图，可以通过比较验证信号的时延不影响匹配滤波的输出信噪比，及不同信号信噪比与信号波形无关，只与信号能量有关(Matched filter to achieve the two simulation procedures, each of the programs to generate the four plans, you can verify by comparing the signal delay does not affect the matched filter output signal to noise ratio, and different signal-noise ratio and signal wave has nothing to do only with the signal energy relevant)
