该程序涉及了M序列的生成，以及相关辨识法的基本实现和概念。(The procedure involves the M-sequence generation, as well as the basic realization of the identification method and concepts.)

详细介绍了轨道方程，轨道六要素，以及坐标计算方法，包括椭圆轨道面坐标、大地空间直角坐标以及经纬度坐标的计算方法(The orbit equation, the six elements of orbit and the coordinate calculation method are introduced in detail, including the calculation method of elliptical orbit, plane coordinates, geodetic space, rectangular coordinates and longitude and latitude coordinates)

这是一个系统的音频素材,可以用在音频编程中(This is a system of audio material, can be used in audio programming)

说明：  模拟蚂蚁和食蚁兽的生存规律。在20X20的网格世界里，每个生物每次可向四个方向移动（但不会移除网格边缘），食蚁兽会吃掉在他目标处的蚂蚁(The goal for this programming project is to create a simple 2D predator-prey simulation. In this simulation the prey are ants and the predators are doodlebugs. These critters live in a world composed of a 20x20 grid of cells. Only one critter may occupy a cell at a time. The grid is enclosed, so a critter is not allowed to move off the edges of the world. Time is simulated in time steps. Each critter performs some action every time step.)

数字滤波器的MATLAB实现,很实用，非常好，欢迎下载不用上传就能下载(FIR)

用MATLAB对图片进行预处理，均值滤波和高斯函数去除噪音(Using MATLAB for image preprocessing, mean and Gaussian filter to remove noise)

给出了通过MATLAB设计FIR滤波器的程序，只需要输入滤波器类型和参数就能设计出特定滤波器，并产生DSP需要的数据，很有意义。(MATLAB is given through the FIR filter design process, only the type and parameters of input filter will be able to design a specific filter, and DSP have the data needed and meaningful.)

II滤波器的chebyshev滤波器的C语言程序设计。(II Filter chebyshev filter C Programming Language.)

特征值分析，便于模态分析电网稳定态态势分析和薄弱环节识别(Eigenvalue analysis, to facilitate modal analysis grid steady state trend analysis and identification of weak links)
