说明：  课程设计时编写的matlab程序代码，基于matlab GUI界面设计,鲁棒性好，性能优越，针对EMD方法的不足,基于分段非线性权重值的Pso算法，仿真效果非常好。
( Course designed to prepare the matlab program code, Based on matlab GUI interface design, Robustness, superior performance, For lack of EMD, Based on piecewise nonlinear weight value Pso algorithm, Simulation of the effect is very good.)
