也是从淘宝花几十买的GPS源代码，c#语言编写，望大家下载参考练习(Also from the taobao spend dozens of buy GPS source code, c# write, hope everyone download reference contact )

voice transformation good algo

轨迹跟踪 用PID控制器或者模糊控制器来控制小车的行走。 编写了小车能绕过障碍并且延者给定的轨迹行走，其中小车的轨迹要事先给定。 (Trajectory tracking fuzzy controller with PID controller to control the car or walking. Prepared a car can go around the obstacle and the extension of those who walk a given trajectory, which tracks car to be given in advance.)

对通信多径分析的SIMULINK文件，可仿真多径、信道衰落等。(SIMULINK file communication multipath analysis, simulation multipath channel fading, etc.)

GPS接收机将捕获结果按比值形式的直方图输出，Matlab程序(GPS receiver will capture the results histogram output of the Matlab program)

说明：  森林大火模拟，新冠肺炎模拟，超级玛丽小游戏开发，各国GDP变化模拟，烟花效果制作(Forest fire simulation, novel coronavirus pneumonia simulation, super Marie game development, GDP simulation of different countries, fireworks production)

GPS应用程序设计，内含GPS卫星原理、方法及详细源代码(GPS application design, including GPS satellite theory, method and detailed source code)

Hi Thanks a lot for your code This code can simulate the chirped DFB laser in time domain

均值变点是统计学中常用的变点分析方法，其主要思想如下： 假设有一组数据，随着某个指标变化（增大），其值逐渐增加并趋于稳定，如何判断在这个过程中是否出现了突变的情况，异样的情况？ 均值变点分析方法提供了一种思路，大概如下： 1 计算总的均值和方差； 2 循环将这组有序数据分成两组，X1，X2 计算各组的均值和方差， 计算总方差与分组方差之和的差； 3 得到变点(The change point of mean is a commonly used change point analysis method in statistics. Its main ideas are as follows: If there is a set of data, as a certain index changes (enlargement), its value increases gradually and tends to be stable. How to judge whether there is a sudden change in the process and the unusual situation? The mean change point analysis method provides a way of thinking, which is as follows: 1 the total mean and variance are calculated. The 2 cycle divides the ordered data into two groups, X1, X2. Calculate the mean and variance of each group. The difference between the sum of the total variance and the group variance is calculated. 3 get a change point)
