有关粒子群算法的源程序，用matlab语言编得，可用于求解函数优化问题(Particle Swarm Optimization on the source, using matlab language was made, can be used to solve the function optimization problem)

小规模OPF计算程序（by FX），中间给出14节点测试系统，缺点计算时间较长（初学者想下点高手的源代码学习学习）(Small-scale OPF calculation program (by FX), in the middle gives a 14-node test system, the disadvantage of longer computing time (beginners would like to point master source code to learn from))

语音增强，基本减谱法MATLAB程序实现(speech enhancement---matlab)

This code uses the output from either make_zeta_u.c file or make_zeta_v.file i.e. it uses the velocity data at any z-level specified by zlevel1. Furthermore, this code filters the velocities, plots the filtered and raw signals at certain specified locations and then creates maps of the velocity time series
