Solution for some problems in Codeforces

This document describe matlab computing environment: Engineering, Technical Computing,Files and File Management,Mathematical Functions and Applications,DataAnalysis and other.

数值分析常用的一些公式，比如jacobi，newton等等。(numerical analysis of some commonly used formula, such as Jacobi, chemotherapy and so on.)

这是用MATLAB仿真平台，实实现无线传感器网络定位算法仿真。 (This is the real implementation of the wireless sensor network localization algorithm simulation using MATLAB simulation platform.)

用于仿真正负线性调频信号在同时极化测量中的性能(Simulation of positive and negative for the chirp signal at the same time measuring the performance of polarization)

基于modelcenter和粒子群算法MATLAB最优化解决装箱问题。包含代码、模块、PPT、课程论文(Based on MATLAB modelcenter and particle swarm optimization to solve the packing problem. It contains code modules, PPT, course papers)

基于matlab车辆文字识别处理方法(Matlab vehicles based on text recognition processing method)

源程序是关于心音信号分析的，可以对心音进行EMD分解(It is about the dealing of heart voice .)

说明：  本文实现了在连续视频数据流中几种不同的运动检测算法，他们都是基于当前帧图像和前一帧图像的比较，程序使用了AForge.NET framework库。其中的示例代码支持下面几种视频格式：AVI文件、网路相机的JPEG和MJPEG，本地的采集设备(USB相机等)。(This article implements a continuous video data stream in several different motion detection algorithms, they are based on the current frame and previous frame image comparison, the program uses the AForge.NET framework library. Sample code which supports the following video format: AVI file, network camera JPEG and MJPEG, the local collection devices (USB cameras, etc.).)

采用轮廓跟踪法，得到两条曲线的坐标集，再通过求质心确定两个基准点 (This function is used to get two basis points between fingers )
