专门介绍利用matlab软件进行时间-频率分析的电子书，希望对大家有帮助(Devoted to using matlab software for time- frequency analysis of the e-book, and I hope all of you to help)

matlab code for readind accelerogram files,useful for seismologists

describe how to perform NDFT algorithm with the sequence

说明：  分布式压缩感知，DCS_SOMP算法。用于稀疏信号的分布式恢复。(Distributed compressed sensing, DCS_SOMP algorithm. Distributed for sparse signal recovery.)

空间前方交会，对于2张影像，已知其外方位或相对方位，求地面坐标或模型坐标(Space forward intersection, and 2 images, known its exterior orientation or relative orientation, for the ground coordinates or model coordinates )

图像骨架化，处理效果明显，希望能够帮助大家学习。(Image skeleton, treatment effect is obvious, hoping to help you learn.)

主要介绍了matlab7.0的基础知识和使用技巧包括（数值运算，符号运算，图形处理）及强大的编程功能和各种实际应用(It mainly introduces the basic knowledge and skills including the use of (numerical computation, symbolic computation, graphics processing) and a powerful programming features and a variety of practical applications)

相似度算法的实现， 在利用支持向量机进行模式分类的时候，有时需要考虑到实时性，为了提高实时性，则利用相似度算法减少样本集个数，从而减少训练时间和支持向量的个数，使得建立起的向量机实时性提高。(Similarity algorithm, support vector machine in pattern classification, it is sometimes need to take into account the real-time, in order to improve real-time, the use of similarity algorithm to reduce the number of sample collection, thus reducing training time and the number of support vectors， improve the real-time of established Vector Machines.)

针对带时间窗的车辆配送问题，用遗传算法，有很多程序，这些程序都是对遗传算法中需要的函数注释以及函数用途说明。并且画图来看遗传算法的优化过程和迭代次数及最优解(For vehicles with time window distribution problem, using genetic algorithms, there are many programs that are required for the function of the genetic algorithm function uses notes and instructions. And drawing view genetic algorithm optimization process and number of iterations and the final result)
