《matlab在数学建模中的应用》卓金武版，从数学建模的角度介绍matlab的应用。书中内容完全是根据数学建模竞赛的需要而编排的，涵盖了绝大部分数学建模问题的matlab求解方法。源码为《Maltab在数学建模中的应用》的源程序和数据。 ("Matlab in mathematical modeling, " Zhuo Jinwu version, from the mathematical modeling point of view on the application of matlab. The book content is based entirely on the needs of mathematical modeling contest arranged, covering the majority of matlab mathematical modeling method for solving the problem. Source for the "Maltab in mathematical modeling, "the source code and data. )

说明：  一个统一的求无约束优化极值函数，方法名由参数传入例如：fmins(无约束方法，一维搜索方法，目标函数，初始点，精度) (A uniform evaluation of unconstrained optimization extremal functions, methods, for example, by an argument: fmins (unconstrained one-dimensional search method, the objective function, the initial point accuracy))

QPSK modulated signal generating

matlab 的基本操作书籍，对初学matlab很有用，很值得推荐(The basic operation matlab books, matlab very useful for beginners, it is worth recommending)

说明：  基于压缩感知思想的图像分块压缩与重构方法 考虑到大多数图像信号信息分布有差异, 编码端, 在对图像分块的基础上, 融合熵估计 和边缘检测方法计算各图像块的信息含量, 再从两个不同的角度进行分类采样: 依据信息量多少将图像块分为平滑、过渡和纹理3 类, 使用不同的采样率采样 依据信息量的分布特征, 采用不同的采样率分配策略进行采样. 在解码端, 根据不同类型的图像块构造不同的线性算子进行重构, 再运用改 进的迭代阈值算法去除块效应和噪声. 实验证明, 算法在提升图像重构质量的同时缩短了重构时间,并且对纹理边缘多的图像的重构效果较其他方法理想.(Considering that most information of the image signal difference distribution, the encoding side, in the right image sub-blocks based on the integration entropy estimation And edge detection method for calculating the information content of each image block, and two different angles classification sampling: The number of image blocks based on the amount of information into a smooth, transition and texture three classes, using different sampling rates based on the amount of information distribution characteristics, using different sampling sampling rate allocation strategy. in the decoding side, depending on the type of image blocks to construct different linear operator reconstructed, re-use change Iterative thresholding algorithm into blockiness and noise removal experiments show image reconstruction algorithm to enhance the quality while reducing reconfiguration time, and much of the texture edge image reconstruction results are satisfactory compared to other methods.)
