BP神经网络作业含程序

说明：  用matlab平台编写潮流计算程序的具体过程，通过实例证明基于牛顿-拉夫逊法的潮流计算程序具有收敛速度快、占用内存小的优点(The specific process of using the matlab platform to compile the power flow calculation program. Through examples, it is proved that the power flow calculation program based on the Newton-Raphson method has the advantages of fast convergence speed and small memory consumption.)

基于多线程的VC++高效率文件搜索代码，若是高速硬盘的话，那文件搜索的速度就更快了，其实很多时候，搜索文件的瓶颈是硬件本身，特别是硬盘转速，像这种多线程的文件检索，理论上处理速度是很快，但需要硬盘跟得上才可以。

说明：  1到33的任意6个数字，他们之和加起来是61，或者改掉sum数字，让他们和为你想要的数字(1 to33Any 6 numbers, and they add up to 61, or get rid of sum numbers, and make them as the number you want )

北斗GPS双模在利用“当前”统计模型并利用kalman滤波时，其系统噪声和观测噪声未知且时变，而且加速度上下限不能自适应于未知运动规律的无人飞行器当前加速度，导致导航精度降低。该程序是相应的MATLAB仿真程序。(Beidou GPS dual mode uses the "current" statistical model and the Kalman filter. Its system noise and observation noise are unknown and time-varying, and the upper and lower limits of acceleration can not be adapted to the current acceleration of the unknown motion law of the UAV, resulting in the reduction of navigation accuracy. The program is the corresponding MATLAB simulation program.)

说明：  本模型里包含几个三维模型重建的模型，对这方面感兴趣的可借鉴学习(This model contains several 3D model reconstruction models, which can be used for reference by those interested in this aspect)

对于使用Allegro做Layout的同行们来说，使用Skill开发的各种各样的小工具无疑会及大地提高绘图效率，这里提供一款对齐工具，安装方法和使用方法在压缩包里有说明，欢迎使用。

，有3种内置的主题，它带有时钟表盘界面和数字刻度，简单实用(There are three built-in themes. They have a clock dial interface and digital calibration. They are simple and practical.)

简单实用，方便利用，实现了BP神经网络在C#下的编程和学习，更加方便和利用。
