粒子群算法的寻优算法，非线性函数极值寻优，MATLAB的经典算法(Particle swarm optimization algorithm, nonlinear function optimization extreme, MATLAB classical algorithm)

电力系统稳态潮流程序，极坐标和直角坐标程序(Power system steady trend procedures, polar and rectangular coordinates program)

Matlab生成UG凸轮曲线 本人原创。我任务就凭这一个课件，我就能成为会员，呵呵。(Matlab generate original UG I cam curve. My task in itself was a courseware, I will be able to become a member, huh, huh.)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)
