人工产生swissroll数据集，方便一些降维方法的效果验证(Swissroll generate artificial data sets to facilitate some of the effects of dimensionality reduction methods to verify)

粒子群算法求解最优化算法的MATLAB程序！！！！(Particle swarm optimization algorithm for solving the MATLAB program! ! ! !)

以前使用matlab和vc混合编程都使用的是先将m程序用mcc转化成dll，再在vc中调用 的方法。这种方法对比较复杂的m文件很方便，但是对一些小的程序，如曲线可视化、计算矩阵特征值等，对这些只需要一两行代码的小程序，再使用dll就得不偿失了。经过试验后，发现可以直接在C++程序中调用matlab c/c++ math & graphic library的函数。(before using Matlab and vc mixed programming using the first procedure used mcc m into dl l, then vc call method. This method of complex documents m very easy, but for some minor procedures, such as curve visualization, matrix eigenvalue calculation, and so on, these are just two lines need a small procedure code, reuse dll on the loss outweighs the gain. After testing, can be found directly in the C Programming Calling Matlab c/c math)

地球坐标系ecef坐标与地理坐标系(bj54/wgs84)转换。(Ecef coordinate system and geographic coordinates (bj54/wgs84) conversion.)

说明：  使用MATCOM使VC与MATLAB混编的小例子(VC and MATLAB using the mixed MATCOM small example of)

说明：  关于定时同步的Matlab仿真代码，采用锁相环技术实现(Matlab code for Timing recovery using PLL)

最小费用最大流问题是经济学和管理学中的一类典型问题。在一个网络中每段路径都有“容量”和“费用”两个限制的条件下，此类问题的研究试图寻找出：流量从A到B，如何选择路径、分配经过路径的流量，可以达到所用的费用最小的要求。(Minimum cost maximum flow problem is economics and management in a class of typical problems. Each path in a network has the " capacity" and " costs" two limiting conditions, such problems of trying to find out: Flow from A to B, how to choose the path, the path of the flow through the distribution can be achieved The use of the minimum cost requirements.)

基于LBP的图像特征提取算法,检索效果大家可是自己实现试试，这种算法还是比较有优势的，但还需要很多改进(image retrieval algorithm based on LBP)

设计一个合成信号，合成信号包含30H、50Hz、80Hz，可以用正弦或余弦或雷克子波，要求消除50Hz信号(Design a synthetic signal, synthesized signal contains 30H, 50Hz, 80Hz, can be used or Ricker sine or cosine waves, requires the elimination of 50Hz signal)

平面刚架结构计算，能够输出结构内力和位移图形。但是在用之前要自己编辑节点信息和作用力信息(Plane frame structure calculation)
