用matlab在极坐标下画天线方向图，可以运行，已经测试过(In the polar coordinates with matlab draw Antenna)

MATLAB提供了强大的计算和图形功能，通过MATLAB编程实现蚁群算法求解TSP问题(MATLAB provides a powerful computing and graphics capabilities, through the MATLAB programming ant colony algorithm for TSP problem)

说明：  全波频率相速度分析，可以分析软硬地层，不同层数的底层(Full-wave frequency phase velocity analysis, to analyze hard and soft strata, different layers of the underlying)

此源码中包含了电磁场中的电偶极子matlab 仿真，及微波与天线中常用到的阻抗圆图matlab仿真。(This source contains electromagnetic field in the electric dipole matlab simulation, and commonly used in microwave and antenna to the impedance circle diagram matlab simulation.)

Corrects lightening using a quadratic fit.

The distribution network has characteristics different from the transmission system. Distribution networks are commonly 1. three-phase unbalanced 2. radial with sometimes weakly meshed topology 3. with high resistance to reactance (r/x) rations here, an equivalent current injection method is used in rectangular coordinates to analyse the given radial distribution system. The FDLF method uses the NR-algorithm, with a constant Jacobian matrix. This matrix is further decoupled into two identical sub-Jacobian matrices.

高斯核函数。可以用来进行调用，对图像进行平滑滤波，也可以进行多尺度分析(Gaussian kernel. Can be used to make calls, image smoothing filter can also be multi-scale analysis)

说明：  噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)

MATLAB6.0数学手册 本教程提供了使用MATLAB的实践性指导，它基于MATLAB6.0版，内容由浅入深，特别是本书对每一条命令的使用格式都作了详细而又简单明了的说明，并配备了例题加以说明其用法，因此，对于初学者自学是很有帮助的；同时，又对数学中的一些深入问题如数值分析、稀疏矩阵、优化理论以及模糊数学等问题进行了较为详细的论述，因此，该书也可作为科技工作者的科学计算工具书。(MATLAB6.0 Mathematics Handbook)
