LDA

数字信号处理中Fourier变换的基本验证。本人验证过，有注释，运行良好。(Fourier transform in digital signal processing basic authentication. I verified, there are notes, running well.)

说明：  ADMM是一个高效的优化算法，可以用在很多领域中，1范数是一种常用的目标函数。(ADMM is an effective, fast optimizing algorithm and can be used in many applications. 1-norm is a commonly used objective function.)

一种用于实现粒子滤波的matlab代码,带中文注释(A particle filter used to realize the matlab code, with English Notes)

说明：  matlab的函数目录，，作为初学者的函数字典，，很有参考价值(matlab function directory, as a function of beginners dictionary, a good reference)

在此代码所使用的算法是从以下引用： S Gillijns等人“什么是集合卡尔曼滤波和它工作得如何？“ 2006年美国电力系统及其控制会议，明尼阿波利斯，美国明尼苏达州六月14-16，2006，页4448-4453。(The algorithm used in this code is referenced from the following: S Gillijns et al "What Is the Ensemble Kalman Filter and How Well Does it Work?" Proceedings of the 2006 American Control Conference, Minneapolis, Minnesota, USA, June 14-16, 2006, pp 4448-4453.)

简单的采样，设计一个输入序列，实现其采样，绘出采样后的时域波形(Simple sampling design an input sequence, to achieve its sample, drawn after the time-domain waveform sampling)

这是<matlab程序设计教程>的书籍源代码。(this is the book code of matlab program design course)

可用于拟合化学分析中的一元线性回归并绘制残差图，找出可疑数据，对化学分析工作者很有用！(Caculated the linear degree and residues of all values you got.Very important for the chemical engineers and scientists.)
