非线性方程的数值解法，在matlab环境下运行成功，集成了牛顿法，弦割法和抛物线法(The numerical solution of nonlinear equations in matlab environment running successfully integrates Newton method, cutting method and the parabola method chord)

线性预测编码（LPC）算法压缩语音。MATLAB实现。计算预测系数和增益。(Linear predictive coding (LPC） algorithm )

利用MATLAB编写的高斯消去法，很好用，也很实用(using MATLAB write Gass)

PCA是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。本程序实现了基于PCA特征脸的人脸识别。(PCA is a major contradiction to grasp things, statistical analysis, it can parse out things from multiple main factors, revealing the essence of things, simplifying complex issues. This program implements the features of face recognition based on PCA.)
