运用matlab进行下个点的预测分析，并画出了预测误差示意图(use Matlab for the next point forecasts and analysis, and the mapping out of the prediction error Map)

本书把MATLAB 当作一种技术编程语言来教，向学生展示如何编写简洁高效，有充分 根据的程序。本书不主张把MATLAB 数以百计的函数全部介绍给大家，而是教给学生怎样 使用MATLAB 语言，以及如何使用网上在线工具去加载你所需要的函数。本书的前六章是 “编程设计介绍”的课程，专门为大一的工科学生而设计编写的。这部分内容以9 周，每周 3 个小时教学为宜。其余的章节涵盖了一些高级的主题，例如输入输出接口（input/output interfaces）和图形用户界面（GUI）。这些章节可能需要更长时间的学习，也可以作为使用MATLAB 的工科学生和有经验的工程师的参考。(The book as a technique to MATLAB programming language to teach, to show students how to write a simple and efficient, there is a sufficient basis for the program. This book does not advocate a function of all the hundreds of MATLAB to introduce to you, but to teach students how to use MATLAB language, and how to use on-line tools to load the function you need. The first six chapters of this book is " designed to introduce programming" course, designed for freshman engineering students designed to write. This part to nine weeks, three hours a week teaching appropriate. The remaining chapters cover some advanced topics, such as input and output interfaces (input/output interfaces) and graphical user interface (GUI). These chapters may take longer to learn, you can also use MATLAB as a reference for engineering students and experienced engineers.)

利用Mersenne Twister算法产生随机数，并测试和分析了其随机性。 程序中还加入了界面显示。 各个文件为： initGenerator.m： initGenerator函数，用于初始化随机序列的长度和值 generateNum.m: generateNum函数，当index为0时被调用，用于创建624维的移位寄存器数组 extractNum.m: extractNum函数，根据index当前值选择数组中的数生成随机数，同时改变index的值。 main.m: main主函数，输入种子seed和产生数目total，输出产生结果及随机性测试结果 mymy.m和mymy.fig: 用于界面显示的部分，这两个文件会通过界面传入seed和total的值，并调用main函数，在相应的框中显示输出结果。 (According to the algorithm principle on Wikipedia, the Mersenne Twister algorithm to generate random numbers, and test and analysis of its randomness. The program has also joined the interface display. The individual files are: initGenerator.m: initGenerator function used to initialize the random sequence length and value generateNum.m: generateNum function is invoked when the index is zero, and used to create a 624-dimensional shift register array extractNum.m: extractNum function, according to index the current value to select the number to generate random numbers, and change the value of the index in the array. main.m: main function of the input seed to seed and produce the number of total, the output generated results and the randomness of the test results mymy.m and mymy.fig: Part of these two files for interface display interface incoming seed and the total value of, and calls the main function, to display the output in the appropriate boxes.)

说明：  通过并行压缩进行二维信号压缩，提出了一种利用并行压缩传感技术对二维信号进行压缩的新方案。根据这个原理，译码器的重新构造可以并行进行。通过对二维信号进行某些排列，可以确保所有列具有大致相同的密度级别，并且可以使用相同的测量矩阵进行采样。这样可以避免二维信号的矢量化，从而大大减小测量矩阵的尺寸。我们证明，如果排列良好，重建均方误差的上限会更紧。为了说明这一方案，我们将其应用于视频压缩并使用不同帧的排列有两种：参考帧的基于Z字形扫描的排列和非参考帧的基于块测试的排列。仿真结果表明，在相同的压缩比下，峰值信噪比比比在无置换情况下可提高3-7db左右。(we propose a new scheme to compress 2D signals using parallel compressed sensing. According to this seheme, the reeonstruction at the decoder can be performed in parallel. By performing certain permutation on a 2D signal, all columns are insured to have approximately the same density level and can be sampled using the same measurement matrix. In this way, vectorization of a 2D signal can be avoided, and thus the size of the measurement matrix can be dramatically reduced. We prove that with a good permutation, we can have a tighter upper bound on reconstruction mean square error. To illustrate this scheme, we apply it to video compression and use two kinds of permutations for different frames: the zigzag-scanbased permutation for reference frames and the block-test-based permutation for non-reference frames. Simulation results show that under the same compression ratio, the peak signal-to-noise ratio can be improved by approximately 3-7 dB compared to the case without permutation.)
