人脸识别Adaboost源代码,用matlab编写实现，使用Adaboost算法进行人脸检测(source code for face recognation using Adaboost)

历史交通流预测，采用matlab编程，预测效果很好(Historical traffic flow forecasting, using matlab programming, forecasting good results)

心音信号的处理分析，包含信号采样、截取、小波分解、阈值去噪、信号重构(Processing and analysis of heart sound signals, including signal sampling, interception, wavelet decomposition, thresholding, signal reconstruction)

LQR最优控制，可以应用于基于磁流变阻尼器汽车悬架等半主动控制(LQR optimal control can be applied to semi-active control of vehicle suspension based on MR damper.)

说明：  典型关联分析(Canonical Correlation Analysis，以下简称CCA)是最常用的挖掘数据关联关系的算法之一。(Canonical Association Analysis (CCA) is one of the most commonly used algorithms for mining data association.)

数字方阵，实现基本的方阵功能，保证功能的完整 (Digital matrix)

Modèle de la machine asynchrone à cage d écureuil dans le repère dq de PARK.

td-scdma链路仿真扩频加扰，绝对能用。(td-scdma Link Simulation spectrum scrambling, absolutely can be used.)

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db
