Plots 3 dimensional plot of a sinc wave

本源码由于提取灯泡边缘，为了进一步的进行图像处理(The source light bulbs because the edge extraction, image processing for further)

旋转矩阵和四原数之间的转换 用于坐标系之间的相互转换(Rotation matrix and the number of conversions between the original four)

在secshortest中我希望只得到一条次短路,结果却出来好几条，因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。(I hope that in secshortest only a short time, the result is out of several, so when used to get at short circuit, can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest.)

一个较好的模拟退火工具箱,主要解决优化问题,(a better toolbox simulated annealing, mainly to solve the optimization problem.)

人造卫星的轨道求解，用的是Brower的方法所得到的解,包含了主要的地球扰动项(The satellite orbit Solving with the solution obtained by the method of Brower)

静电场的matlab计算并生成电场分布和电位分布图像(The electrostatic field is computed by MATLAB, and the electric field distribution and potential distribution image are generated)

计算A加权后的噪声净噪声值并将结果保存到excel文档(Calculate the Netnoise after A-filter and save the result into excel file.)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
