说明：  基于MATLAB的平面六连杆机构运动分析(MATLAB-based planar six-Linkage Kinematic Analysis)

该程序是《图论及其应用》中最小生成树的克鲁斯科尔算法的其中一种描述方法，特点是求解过程和人们手动求解的思路相近。功能是输入一个赋权图的边的编号及其权值，程序返回最小生成树对应的边的编号。编号由用户自己定义，根据结果给出的编号可以由原图绘出最小生成树。(This program can get the smallest tree from a weighted-graph. )

代码描述了多芯光纤的基本传输模型，其中包括了损耗，色散，非线性，以及芯与芯之间的串扰。(Code describes the basic model of the multi-core optical fiber transmission, including crosstalk loss, dispersion, nonlinearity, and between the core and the core.)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.
