blingd_matlab

this is watermark source code. it is good for making programming

说明：  matlab基础教学系列6，一步步送入熟练(the door to matlab)

实现重力反演，提供实例，建立模型正演，然后进行反演(Realize the gravity inversion, provide examples, modeling forward and inversion)

基于前推回代算法的配电网潮流计算，很经典的程序源代码(Based on behalf of the algorithm back to the distribution power flow calculation, it is the classic source code)

说明：  用于求解光纤的TM模，具体信息可以查看m源文件内的说明(TM-mode fiber is used to solve the specific information you can view the description of the source file m)

用matlab语言来实现TSP问题，对于研究TSP问题的人有很大的帮助(TSP problem matlab language of great help for people who study the TSP)

基于粒子群算法的电力系统负荷分配问题（1）数学模型： 以IEEE 3机6节点为工况模型 ，Load=850MW （2）目标函数： minF=∑(i=1，Ng)Fi(PGi)，Fi(PGi) =aiPi2+biPi+ci+Ei，考虑阀点(Valve-Point)效应 （3）约束条件： a.发电机组输出功率上下限约束，即PGi min<=PGi<= PGimax； b.电力负荷平衡约束，忽略网损，即∑(i=1，Ng)（PGi）= PGD(Based on particle swarm optimization of power system load allocation problem)

以速度为11m/s沿x轴做匀速直线运动，通过卡尔曼滤波跟踪目标，作出相应协方差图像，内有注释，根据相应功能可更改注释。(At the speed of 11 m/s, we perform uniform rectilinear motion along the X axis. We track the target through Kalman filter and make corresponding covariance images. There are annotations in it, and annotations can be changed according to the corresponding functions.)

The Schumann resonance frequencies are a set of eigenmodes in the extremely low frequency (ELF) portion of the electromagnetic field spectrum. These frequencies are only present for planetary-like bodies with a substantial ionosphere acting as a perfect electric conductor, thus forming a resonance cavity with the surface. In this example, the Schumann resonance frequencies for the Earth are calculated.

说明：  使用各种方法进行图像特征提取，对特征不明显的图像有很好的效果！(Using a variety of methods for image feature extraction, feature obscure the image of good results!)
