单摆的运动仿真，可以求解小球的速度及角速度，考虑空气阻力对于小球速度的影响(Pendulum motion simulation, can solve the speed and angular velocity of the ball, air resistance into account the impact speed for the ball)

This File is to simulate transmission data with QPSK modulation. Also, using LMS adaptation method for detection in the receiver part.

说明：  我毕设时的MSK编程，，MATLAB，，带有差分编码的，程序比较简洁易懂(I completed the set when the MSK program,, MATLAB,, with differential coding, the procedure is simple and easy to understand)

一份FDAtool使用、参数设置较详细的资料( FDATOOL)

CODE FOR COMPUTATIONAL FRACTAL. YOU CAN USE IN MATLAB SOFTWARE.

《Applied Speech and Audio Processing With Matlab Examples》是Cambridge University Press 2009的新书。大家从书的名字里就能知道这本书是干什么的了。("Applied Speech and Audio Processing With Matlab Examples" is a new book published by Cambridge University Press in 2009. We can learn from it title what the book is used for.)

是一个常规PID控制例子(包括了系统建模部分),控制对象为直升机的俯仰轴角度控制,其数学模型为二阶传递函数.(Is an example of conventional PID control (including the system modeling part), control for the helicopter pitch angle control axis, the mathematical model for the second-order transfer function.)

This utility provides a powerful zooming tool specially designed for the documentation of original and zoomed 2D graphics of images on the same plot. It is composed of two blocks (the secondary axes and the magnifier). The secondary axes, which can be arbitrarily allocated within the limits of the figure, displays the area marked by the magnifier. The highly versatile interface of the on-figure magnifier offers a world of possibilities in a broad range of applications and fields. The Keyboard/mouse or programmatic configuration of this tool allows the user to set her or his own graphic style, to suit the requirements of any publication s editor. More details on interfacing and properties can be found in the .m file.

基于Logistic混沌映射的图像加密 将图像数据转换成二进制数据，并采用Logistic进行混沌序列生成，然后设定阈值将其转换成二值序列，之后，设定加密规则，将二进制图像数据与混沌二值序列进行加密运算，实现图像加密(Based on Logistic chaos mapping image encryption)

说明：  工业图像处理软件，但没有数据库，具体操作说明见(Industry image processing software, but there is no database, see the specific operation instructions)
