求序列向量xn的傅里叶变换和离散傅里叶变换并画出它们的幅频特性和相频特性曲线，验证离散傅里叶变换是傅里叶变换的等间隔采样，验证IDFT和DFT的唯一性(Find the Fourier transform of the sequence xn vector and the discrete Fourier transform and draw their amplitude-frequency characteristic and phase-frequency characteristic curve, verify the discrete Fourier transform is the Fourier transform of equally spaced sampling, verification of IDFT and DFT Uniqueness)

设计一个AC/DC/AC变频器设计，具体参数如下：三相交流输入380V/50Hz，三相输出交流电压500V/400Hz,THD<5 ,负载为一般的阻感负载，功率5000W。(Design of a AC/DC/AC converter design, the specific parameters are as follows: Three-phase AC input 380V/50Hz, three-phase output AC voltage 500V/400Hz, THD < 5 , as a general resistive load inductive load, power 5000W.)

说明：  lagrange插值 快捷计算插值，挺好的.(lagrange interpolation quick calculation of interpolation, quite good.)

互信息相关的一些资料和代码，比较有借鉴意义的，大家可以看一下(Mutual information related to some of the information, more reference, we can look at)

这是一个模式是别里的关于fisher算法实现的广义线性分类器(This is a model other fisher Lane on the algorithm of generalized linear classifier)

说明：  matlab例程，初学者的福音，要的赶快下压，绝对好东西(matlab routines for beginners of the Gospel, to the quickly under pressure, never a good thing)

说明：  负载均衡调度问题：假设有N个任务，需要负载均衡器分配给M个服务器节点去处理。每个任务的任务长度、每台服务器节点（下面简称“节点”）的处理速度已知，请给出一种任务分配方式，使得所有任务的总处理时间最短。CreateData文件(Load balancing scheduling problem: suppose there are n tasks, which need to be allocated to m server nodes by load balancer. The task length of each task and the processing speed of each server node (hereinafter referred to as "node") are known. Please provide a task allocation method to minimize the total processing time of all tasks.CreateData)

利用交又我们有可能由父代个体在子代组合成具有更高适合度的个体。(For this part, you are allowed 30 minutes to write a composition on the topic Why Do People Like to Buy Lotteries?)

给定n位整数任意去掉其中k<=n位，剩下的数字按原次序排列组成一个新的正整数，且这个正整数最小(Given an arbitrary n-bit integers to remove where k < = n bits, the remaining number of original order of the formation of a new positive integer, and that this is the smallest integer)
