介绍了MATLAB工具中的数学工具，是你用MABLAB开发时必不可少的参考书籍啊。(MATLAB tools introduced in the mathematical tools, is when you develop MABLAB indispensable reference books ah.)

说明：  写一个程序，用户依照流行歌曲的人气调查表，将相关数据输入到计算机文件中，计算机按照人气指数将排名前十位的歌曲信息显示并存储到文件中。(Write a program, the user in accordance with the popularity of pop music questionnaire, data will be entered into the computer files, the computer will be ranked according to popularity index of the top ten song information display and store the file.)

这个代码的主要作用是练习用的，可以用它来练习，然后得到提高(The code is based on Practice，so we can use it to make some improvement and maybe it can realize some new functions)

说明：  最短路课程设计，好的啊，需要的赶紧下载啊，哈哈~~~`(The most short-course design, a good, ah, need to quickly download ah, ha ha ~ ~ ~ `)

读书小报告 source code for freinds, 免费版本(small study report freinds source code for free version)

说明：  高等应用数学问题的MATLAB求解高等应用数学问题的MATLAB求解(Advanced application of advanced mathematical problem solving application of MATLAB MATLAB to solve mathematical problems)

说明：  BP算法是为了解决多层前向神经网络的权系数优化而提出来的；所以，BP算法也通常暗示着神经网络的拓扑结构是一种无反馈的多层前向网络(BP algorithm is to solve the multi-layer feedforward neural network weights optimization and put forward Therefore, BP algorithm usually implies that the topology of neural network is a multi-layer feedback-free network)

离散傅里叶变换对于FDTD计算程序很有用( an algorithm resistant to print/scan process is proposed , which is based on block discrete fourier transform)

智能天线技术是第三代移动通信系统的关键技术之一，也是国内外热门的研究课题。由于无线移动通信的信道传输环境具有复杂性和不确定性，存在多径衰落和时延扩展，因此造成了符号间串扰、同信道干扰、多址干扰等，这些干扰降低了链路性能和系统容量，智能天线技术是解决以上问题的方法之一。 本文首先阐述了智能天线和白适应波束形成的基本理论，然后对自适应算法进行了研究。对一些基本的自适应算法最小均方算法、恒模算法及递推最小均方算法进行了分析讨论，用计算机仿真的结果论证了算法的性能。针对相干干扰介绍了空间平滑技术，对传统的相干干扰抑制方法-空间平滑法进行了分析，采用改进算法有效降低了空间平滑算法的运算量。对信号波达方向(DOA)的估计是智能天线研究的另一关键问题。第四章在介绍了阵列信号处理方法的基础上，先简单介绍了Bartlett、Capon、MUSIC等空间谱估计算法，分析了信源数目过估计与欠估计情况下的MUSIC算法性能，提出一种改进算法，在信源数目有误差的情况下该算法的性能良好。第五章针对多径干扰环境，在分析MMUSIC算法的基础上，本文提出了基于低秩矩阵逼近法的改进MUSIC算法(In this paper, firstly, the author illustrates the principles of smart antenna and adaptive beam forming, and then introduces some typical adaptive algorithms, the LMS ,CMA and RLS algorithms are analyzed and discussed and simulate them in the computer to prove their capability. but they have the disadvantage of high complexity, so they are not fit for practice. The paper analyses the conventional method rejecting spatial smoothing coherent interfering signals, which is spatial smoothing technique)

The time is calculated and converted to 64-bit in the first and second lines and then converted to local time zone before being converted to a SYSTEMTIME structure. Last of all the system time is set.
