采用高斯变异改进基本萤火虫群优化算法，得到很好的效果(Gaussian variation improve basic fireflies swarm optimization algorithm to get good results)

可实现Butterworth滤波器 的功能 使图像处理的一个重要功能部分(Butterworth filters can realize image processing functions to an important functional part)

用matlab编写的newmark－belta法求解结构动力响应(Prepared using matlab newmark-belta method for structural dynamic response)

pARTIAL TRANSMIT SEQUENCE is very effective technique for papr reduction in OFDM.It divide OFDM sequence into several disjoint sub sequences and convert to time domain then Combine with complex phase factors to reduce PAPR.In this code matlab simulation of this technique is implemented

信号包络，提出信号包络，便于观察信号波动过程，非常有用(Signal envelope, put forward the signal envelope, easy to observe the process of signal fluctuations, very useful)
