DNA编码序列算法，很好用的，可以学习学习(DNA sequence encoding algorithm, very good use, you can learn)

利用中心差分法求解振动微分方程，从而得到线性或非线性结构的振动特性。(Solving differential equations of vibration by central difference method)

层次分析法和两种matlab实现方法，利用matlab编程用俩种方法实现了层次分析法，并且有实例进行分析和验证。(Analytic hierarchy process (ahp) and two matlab methods, the paper achieve the analytic hierarchy process (ahp) by using matlab programming with two kinds of method, , and a instance is analyzed and validated.)

system identification base least square error on step peridiction

关于信号处理方面音效移频中解析信号的产生方法，该方法让人耳目一新，通过先设计频域，再求逆，时域上进行采样，得到两个FIR滤波器逼近希尔伯特变换器。(Aboat an efficient method of analytical signal generation in audio frequency shift.This method refreshing, first design in the frequency domain, then sampling in the time domain, getting two FIR filters approximate Hilbert transform.)

基于海洋综合观测平台的海洋信息处理技术是海洋预警系统开发的技术支撑,建立基于海洋综合观测平台的海洋信息处理及预警系统(Based on integrated ocean observation platforms of marine information and technology is the deal with Ocean early warning system developed by technical support, set up based on integrated ocean observation platforms of marine information and deal with early warning systems)

these are the different matlab codewhich will help u to make different types of matlab codes thanks alot
