点电荷电场与电势模拟程序(matlab语言)，对研究物理仿真的朋友会有帮助(Point charge electric field and electric potential simulation program (Matlab language), the friends of the physical simulation will be helpful)

hello sent this for in rar filr

直流电源逆变器向直流电机提供动力，观察直流电流输出电压电流波形(DC power supply inverter to provide power to the DC motor, DC output voltage and current waveform observation)

Commande vectorielle d 1 MADA double alimentaion

前馈ANC系统的模型，但是，不详细，可以参考！(the model of two earphone active noise control)

用于视频车辆检测，使用matlab语音，测试结果准确率达90 (For video vehicle detection, the use of matlab voice, test results are accurate 90 )

是数学竞赛的往年考题！！希望对大家有用！！(Mathematics exam in previous years the competition! ! Hope it useful! !)

给定控制顶点，绘制出B样条曲线，不是很好，大家可以学习一下(The given control vertex arrays, fitting out of B spline curve, is not very perfect, we can learn about it )

its an rectifier circuit with PWM PI control technique for high accuracy and better output with very low THD.

可以根据图中点的位置判断连接关系，然后搜寻图中的MDS（最小支配集合）(You can determine the connection between the position according to FIG midpoint, then search graph MDS (Minimum Dominating Set))
