核密度估计的源码，kernel density estimation，从官方渠道获得(Source kernel density estimation, kernel density estimation)

matlab导入txt格式数据后，能对数据数据二次平滑(Two times smoothing )

主要介绍了dvhop算法的源代码，先计算平均每跳的距离，再根据跳数求出锚节点与未知节点的距离，再用三边测量法求出未知节点坐标(Dvhop algorithm introduces the source code, to calculate the average distance of each jump, then jump a few calculated in accordance with anchor nodes and unknown distance from the node, and then calculated trilateration unknown node coordinates)

i guess this is the last time

三相背靠背交流直流交流simulink仿真模型，采用PWM调制，电压闭环控制(VSC1 controls DC link voltage (Vdc 680 V)and VSC power factor on 60 Hz grid (PF 1.0)PWM frequency 33*60 1980 Hz VSC2 controls load voltage (VLL 380 Vrms 50 Hz) PWM frequency 2000 Hz )

欧拉角表示法具有简便、几何意义明显等优点，同时姿态敏感器可以直接测出这些参数，能较方便地求解用这些姿态参数描述的姿态动力学方程。但采用欧拉角的姿态描述方法存在奇点问题，且需多次三角运算。而采用四元数表示方法则可以避免这些问题。(conversion between euler angle and quaternion method)
