说明：  这个文件里包含了画隐函数立体图的方法，简便使用，容易学习。(it about a technique of implicit functions diagram.)

试过很多matlab机器人工具箱，这个是好用的，带使用说明书和例子。(Tried of many-matlab robots Toolbox, this is easy to use, with manual and examples.)

说明：  归一化梯度 matlab编写的一种算法，以及处理过程(Normalized gradient)

该程序是用L-Z复杂度算法检测VF信号的算法，并用的MIT-BIH数据库中的数据加以实现的。(The program is used LZ complexity algorithm to detect VF signal algorithm, and use the MIT-BIH data in the database to be achieved.)

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(The matlab program to achieve the target image segmentation and extraction technology, the annex of the procedures for license plate detection and recognition, for example, the effect is very good.)

离散的kalman滤波，计算信号的滤波值、预测值，估计误差及预测误差(kalman filter)

说明：  详细介绍了如何使用ModelSim进行仿真.(it will teach you how to use the ModelSim to simulink.)

使用波模控制的直接转矩控制构建的系统，给出了相应的仿真模型及结果。(Wave mode control using the direct torque control system is built, gives the corresponding simulation model and results.)

Here, an implementation of Fast Decoupled Load flow is matlab platform is done. This is used for Load flow studies (Electrical).

说明：  实现声音时域分析，达到对声音信号短时能量的图形描绘分析(Time domain analysis to achieve the sound, the sound signal to the graphic description of short-term energy)
