通信系统仿真可能会要用大的子函数，子函数，源文件，希望对大家有用(Communication system simulation may be to use a large subroutine, subroutine, source files, want to be useful to everyone)

说明：  ecg信号检测程序。非常好用！！！ecg信号检测程序。非常好用！！！(ecg detection program---very good，ecg detection program---very good，ecg detection program---very good，ecg detection program---very good，)

自己编写的kalman滤波例子，实现对X,y坐标跟踪的例子，欢迎大家参考提意见(themselves prepared Kalman filtering example, the realization of X, y coordinates tracking example, Welcome reference comment)

基于maltab的谱分析，信号的频率分析、频谱分析等(Based on spectral analysis maltab, the frequency of the signal analysis, spectrum analysis)

利用背景预测方法进行弱小目标检测，取得了比较好的效果。是用源图像减掉了背景得到残差图像进行检测的(dim target tetection using background prediction method)

HCL Test Paper Pattern (HR Interview, Techincal And Aptitude) Aptitude is an online round. There were only 2 rounds for us. 1.Aptitude(2 Apps for IT and CSE) A. General aptitude(60 que in 50 min) B. Technical Aptitude(Data Structures,C,OS)[25 que in 20 min]

粒子群算法优化函数，取得很好的精度，满足了学习的要求！(Particle swarm optimization function, to achieve good accuracy)

通过matlab用两种方法实现主成分分析(Matlab two ways, through the achievement of principal component analysis)

This addresses the use of ANFIS function in the Fuzzy Logic Toolbox for nonlinear dynamical system identification. This also requires the System Identification Toolbox, as a comparison is made between a nonlinear ANFIS and a linear ARX model.

一个用matlab写的特征挑选，大家试试吧！(Using matlab to write a feature of the selection, we give it a try!)
