根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

实现了用burg方法进行谱估计,输出有系数矩阵，方差，各阶预测误差等等(it realize the Spectral Estimation using the methed of burg.)

说明：  频谱细化小程序（基于czt的频谱细化MATLAB程序）(Detailed spectrum of small procedures (based on MATLAB refinement spectrum czt Procedure))

TDMS的文件读取到Matlab。 优点： -支持读取v2的文件 -不需要使用NI的DLL，因此它不需要32位窗口 - 支持隔行扫描数据 -只允许读的名称及属性，以得到一个文件是什么感觉快 - 允许读数据的特定子集 (Reads TDMS files into Matlab. Advantages: - supports reading v2 files - doesn t require the NI DLL, thus it doesn t require 32bit windows - supports interleaved data - allows only reading names & properties to get a quick feel for what is in the file - allows reading specific subsets of the data)

Reduce the number of data points using a spanning tr(Reduce the number of data points using a spa nning tr)

这个使用C编的stop operator，是s函数的格式。stop operator是Preisach 模型的一种基本模块。线性组合即成preisach 模型。(Stop operator, the C series is the format of the s function. The stop operator is one of the basic module of the Preisach model. The linear combinations Serve preisach the model.)

用C开发程序时调用Matlab的功能，为精通Matlab编程一书中附带的程序，感觉比较适合初学者。(C development process called Matlab functions, Matlab programming proficiency for a book accompanying procedures, feeling more suitable for beginners.)

粒子滤波重采样方法，目的在于克服粒子滤波计算过程的粒子贫化和粒子退化的问题(resampling method used in particle filter)

一个感应电机设计过程的MATLAB文件，省去手工计算的麻烦，也可以自行封装成面对对象的exe文件。(An induction motor design process of MATLAB files, save the trouble of manual calculation, it can be packaged into the exe file the face of the object.)
