BM3D_v1.7.6_x64

来自国外的2D phase unwrap 的matlab源码。基于branch cut(剪枝法) 及FloodFill（洪泛法）实现。速度很快。相位解卷绕精度高。(2D phase unwrap from abroad matlab source. Based branch cut (Pruning) and FloodFill (flooding method). Fast. Phase unwrapping high precision.)

说明：  模型阶次的辨识,各种模型参数辨识方法一般需要假定模型的结构已知，实际上在多数情况下这是不现实的。当没有模型结构的先验知识时，需要利用系统的输入输出数据来确定模型的结构。(Identification of various model parameters generally need to assume that the model structure is known, in fact, in most cases this is unrealistic. When no prior knowledge of model structure, the need to use the system input and output data to determine the model structure.)

Grid_connected _PV_P&O_MPPT

file includes least square and least mean in matlab

mean shift 用于视频序列的目标跟踪，有例子，用的MATLAB2013a，亲测，可用，改下读图地址即可(mean shift ，Target tracking for video sequences, there are examples of using MATLAB2013a, pro-test, available under change the digitizing address. )

基于原始粒子群算法和原始模拟退火算法的结合。具有收敛性好，计算速度快的优势(Combined with the original particle swarm algorithm based on simulated annealing algorithm and the original. Has a good convergence, high calculation speed advantage)

雷达信号瞬时自相关处理，计算信号瞬时频率，计算雷达信号参数等(instant auto-corelation)

曲面拟合的程序，网上很多地方有，但是都是错的，我改正后上传了(Surface fitting procedure, there are many places online, but it is wrong, I uploaded the corrected)

四个偶极子天线的特性分析。包括场特性，方向图等(Four dipole antenna characteristic analysis. Including market characteristics, such as the direction of graph)
