说明：  基于PCA实现的人脸识别，识别率达到80 以上(Face Recognition Based on PCA implementation, the recognition rate of more than 80 )

现代信号谱估计算法的matlab代码 调用函数代码(spectral analysis of signals)

三次样条插值，很不错的插值算法，值得参考(Cubic spline interpolation, the interpolation algorithm is pretty good, it is also useful)

k均值的 咱们做非监督分类都用过 不想理解他的原理吗 很重要(k mean we do not want unsupervised classification are used to understand his theory is very important to you)

说明：  《MATLAB语言与自动控制系统设计》第二版，机械工业出版社，魏克新等编著。介绍了各种经典控制器的matlab设计方法。(MATLAB Language and Control System Design，Second Edition, China Machine Press, WeiKexin, eds. Introduced a variety of classical controller design methods in matlab environment.)

说明：  定时恢复仿真程序，可以解决定时不准确造成的定时错误(timing recovery simulation program can solve the timing of inaccurate timing error)

matlab实现费希尔法（fisher法）实现对样本的分类，上载的是txt文本文档。(matlab in fisher sorting)

convolutional networks for image processing

Simulate MMSE_Receiver_for_DS_SS_in_AWGN_Channel

说明：  在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numubrical)
