在一张表中标注了CTFT，DTFT，DFT之间的对应关系，列出公式，给出了简单认证，同时加上文字说明(Marked in a table of correspondence between CTFT, DTFT, DFT between lists formula gives a simple certification, plus text)

本程序应用了混沌序列作为伪码生成器对直接扩频系统进行了仿真，并在多用户情况下作了仿真(the application procedures as a chaotic sequence of pseudo-code generator directly to the spread spectrum system simulation, Multi-user and the circumstances made Simulation)

基于混合高斯模型的matlab代码，用于求概率问题，可行，已经运行过了(Based on Gaussian mixture model matlab code for the required probability problems, feasible and has been running over)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

通过不同的时间段去选择退出时间，这样有效的控制操作。 (limited time)

MATLAB code to generate a sine wave when frequency and other characteristics are given.

说明：  主成分分析法将图像分为低秩部分和稀疏部分(Principal Component Analysis (PCA) divides images into low rank and sparse parts)

MATLAB高斯消去法解方程组，我调试过了，可以用的。欢迎大家下载使用！(MATLAB Gaussian elimination solution of equations, I have debug off, and can be used. Welcome to download!)

PID调节器结构简单、参数易于调整，当被控对象精确数学模型难以建立、系统的参数又经常发生变化时，应用PID控制技术，在线整定最为方便。 (PID adjustor simple structure, easy adjustable parameters, when the controlled object mathematical model is hard to build up, the parameters of the system and often changes, application of PID control technology, online setting the most convenient.)

提出了一个混沌系统,并对该系统的基本动力学特性进行了深入研究.得到该系统的Lyapunov指数、Lyapunov 维数,给出了Poincaré映射图以及时域图和相图.运用电子工作平台EWB软件对实现该新混沌系统的振荡器电路进行了仿真实验.经过数值仿真和电路系统仿真证实该系统与以往发现的混沌吸引子并不拓扑等价,属于新的混沌系统.(Presents a chaotic system, and the basic dynamic characteristics of the system were studied. Get Lyapunov exponent of the system, Lyapunov dimension, given the Poincar maps and graphs and time-domain phase diagram using electronic work platform EWB software for implementing the new chaotic system oscillator circuit simulation experiments through numerical simulation and circuit and system simulation confirmed that the system ever discovered chaotic attractor is not topologically equivalent, is the new chaotic system.)
