汽车7自由度simulink仿真模型，详细描述了车辆起自由度模型的构成，在实际仿真中的用车(Automobile 7 degree of freedom simulation model of Simulink, a detailed description of the vehicle up degrees of freedom model constitute, in the actual simulation of car )

四轴飞行器PID控制。Simulink仿真。内外环控制。(Quadcopter PID control. Simulink simulation. Inner and outer loop control.)

Affine Scale Invariant Feature transform..

说明：  一个LDPC的例程使用matlab编写，可直接运行，信道编码程序(a LDPC the use of Matlab routines prepared to be directly run channel coding procedures)

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”，编写程序找出2～5000中的所有完数。(If a number is just equal to the sum of its factors, this number is called &quot complete number&quot , written procedures to identify 2 to 5000 in the number of all finished.)

说明：  整个系统分为数据采集和数据分析两大部分，以友好的图形界面与用户进行交互沟通。 声音数据采集部分实现数据采集功能,根据用户选择的采样频率和预设的采样时间来从声卡获得用户需要的数据。并且将采集到的数据及其频谱图以图形方式很直观的呈现于用户面前。 图像采集分析部分，读入图像后，根据选择，对其进行Linear Conformal、Affine、Projective、Polynomial、Piecewise Linear、Sinusoidal、Barrel、Pin Cushion变换(The whole system is divided into data collection and data analysis of two parts, with a friendly graphical interface to communicate with the user interaction. Sound data collection part of the data collection function, according to user-selected sampling frequency and sampling time to the default user from the sound card to obtain the data needed. And the collected data and the spectrum is very intuitive graphically presented in front of the user. Image acquisition and analysis section, read the image, based on the choice of its Linear Conformal, Affine, Projective, Polynomial, Piecewise Linear, Sinusoidal, Barrel, Pin Cushion Transformation )

IEC协会推荐的电压波动和闪变的测量计算方法，并含相关的IEC标准和国标（这些标准很难找到免费的）(IEC Association recommended voltage fluctuation and flicker measurement and calculation methods, and with the relevant IEC standard and GB (hard to find these standards for free))

说明：  侧向和横摆的二自由度车辆模型,输入为方向盘转角，车速，轮路附着系数(2dof vehicle model including lateral and yaw)
