得到特征方程，采用二分法和黄金分割法搜索梁、板等结构的自振频率(The characteristic equation, and the golden section method using dichotomy search beams, plates and other structure of the natural frequency)

说明：  可用来求解大变形悬臂梁的程序，十分方便简洁，精确(to figure out the deformation of the cantileaver beam)

Matlab M-Files:There are four ways of doing code in Matlab. One can directly enter code in a terminal window. This amounts to using Matlabas a kind of calculator, and it is good for simple, low-level work. The second method is to create a script M-fi le. Here, one makes a fi le with the same code one would enter in a terminal window. When the fi le is “run”, the script is carried out. The third method is the function M-fi le. This method actually creates a function, with inputs and outputs. The fourth method will not be discussed here. It is a way to incorporate C code or FORTRAN code into Matlab this method uses .mex fi les. We will not disucss it here.

一个MATLAB/Simulink模型，关于电动汽车动力电池荷电状态（State of Charge，SOC）估计； 包括参数文件、模型文件两种，模型文件分别仿真了110A恒流、110A脉冲和ECE15工况； 建模采用基于PEGV的电池等效模型对SOC进行估计，并且加入了温度修正等。 模型比较简单，原理清楚，适合对电动汽车动力电池SOC的估计有兴趣的初学者参考学习，学习前请阅读2到3篇基于电池PNGV等效电池模型的动力电池SOC估计方面论文，这样对理解模型更有帮助。(A MATLAB/Simulink model, on the electric vehicle power battery State of Charge, SOC estimates Including the parameter file and the model file, the model file simulates 110A constant current, 110A pulse and ECE15 working condition respectively. The SOC model was used to estimate the SOC and the temperature correction was added. The model is relatively simple, the principle is clear, suitable for beginners interested in electric vehicle power battery SOC estimation, it will be better to read 2 to 3 SOC estimation papers about battery PNGV equivalent battery.)

用于确定分析蛋白质序列上编码区的一个程序，算法虽然有点过时，但还有些参考价值。(Is used to determine the protein sequence analysis of the coding region of a program, algorithm though a bit outdated, but some reference value.)
