chirp信号脉冲压缩，用于雷达信号处理，产生chirp信号后进行压缩，以实现高距离分辨力(chirp signal pulse compression for radar signal processing to generate chirp signal is compressed in order to achieve high range resolution)

说明：  刚刚接触图像检索的同学，对基于特征的图像检索还没有什么概念，利用这个小的程序（里面附有图像和实例）感受一下过程，对于继续研究很有帮助。(Contact with students just image retrieval, the feature-based image retrieval has no concept of, take advantage of this little program (inside with images and examples) feel the process and continue to study for the useful.)

说明：  golden code 一种先进的编码方法 性能优越 复杂度低(golden code, an advanced coding method superior performance, low complexity)

这是一个用于快速独立元分析的程序，调试可用(this is used for fastica)

白噪声中单个正弦信号的频率检测与估计 产生，其中是一高斯白噪声，其均值为0，方差为1。用MUSIC方法估计观测数据中正弦波的频率，并给出白噪声方差()un2uσ 与复正弦波的振幅A的估计值。(A single frequency detection and estimation of the sinusoidal signal in white noise, which is a Gaussian white noise with mean 0 and variance 1. MUSIC method to estimate the frequency of sine wave in the observation data, and gives the white noise variance () estimated value of the the un2uσ complex sine wave amplitude A.)

matlab程序设计关于MATLAB的安装编程调试等(matlab program design on the installation of MATLAB programming and debugging)

matlab神经网络的应用和分析，很好用的 对bp的学习是中帮助(matlab neural network application and analysis)

使用matlab进行仿真，还有pca降维，kl变换方法进行人脸识别的参考论文(Using MATLAB simulation, and the PCA dimension reduction, the KL transform method for face recognition reference papers)

this work, presend a control based stand-alone hybrid energy PV system.

This code is used for extracting texture features in an image
