嵌入式小波零树（EZW）算法的过程详解和Matlab代码。(EZW code 。)

说明：  时间序列分析模型：本程序的目的是模拟一个ARMA模型，然后进行时频归并。考察归并前后模型的变化。(ARMA)

matlab编程（第二版）国外经典入门教材，每章后面有详细的试题，首次加入附录A和B，对于matlab初学非常有帮助！可以进行自我测试，翻译的也比较精准，对于英语程度不够看原版书籍的同学很有帮助！(matlab Programming (Second Edition) foreign classic primer for matlab,can be very helpful for the freshman!)

生成一个正弦信号，并加入白噪声，得到正弦信号以及白噪声的混合信号，通过低通滤波器对白噪声进行处理(generate a sinusoidal signal, and add white noise, sinusoidal signal to be white noise and mixed-signal, through low-pass filter white noise processing)

计算了基模高斯波束的电场，相位，该代码可用来计算光学中高斯波束的相关系数(Fundamental mode Gaussian beam calculated the electric field, phase, the optical code can be used to calculate the correlation coefficient in the Gaussian beam)

本自适应算法，是格型的LMS算法，描述了反射系数对算法的影响，以及LMS算法和格型LMS算法的对比(The adaptive algorithm is grid-based LMS algorithm, the algorithm describes the impact of the reflection coefficient, and the LMS algorithm and lattice LMS algorithm comparison)

关于512位的正余弦表，内有两个数组，分别存放已经算好的正余弦数(About 512 positive cosine table with two arrays were stored has been considered a good number of sine and cosine)

MATLAB下使用viterbi算法进行卷积码的仿真范例。可以用任意配置的卷积码。testConv.m启动仿真，其中用了两种卷积码(一个1/2和一个2/3卷积码）。若要使用硬判决，需修改metric.m文件。其他就没有什么要改的了。解压即可使用。(Under viterbi algorithm using MATLAB simulation examples of convolution codes. Can be used in any configuration of the convolutional code. testConv.m start the simulation, which used two convolution code (a 1/2 and a 2/3 convolutional code). To use a hard decision, modify metric.m file. Nothing else would want to change it. Extract can be used.)

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)
