matlab程序用于地震波的特性分析 时频及频谱分析(Matlab program for seismic wave characteristic analysis Time-frequency and spectrum analysis)

matlab 基本语句描述，及一些基本内部函数，很有用的，欢迎共享，谢谢(Differential evolution algorithm is very popular in recentyears, it iswidely used in complex optimi- zation questionsbecause of it’s easy implementation and has less controlparameters. Butconventionaldifferen- tial evolution algorithm has a problem ofstagnation thatcan stop the algorithm convergence. )

说明：  程序\RS.rar MATLAB程序 谢谢支持(Program \ RS.rar MATLAB program thanks to support)
