S变换的MATLAB实现程序

基础的音频处理matlab程序，设计巴特沃斯低通数字滤波器实现滤波。(Matlab-based audio processing procedures, Butterworth low-pass digital filter designed to achieve the filtering.)

说明：  计算故障分类的每个属性的信息熵，选取最大的作为根节点(For fault classification information entropy of each attribute, select the largest as the root)

奇异值分解用在振动信号降噪，很好用，建议下载(Singular Value Decomposition)

使用matlab语言编写的，用于直方图法的分析，也可以称作众数法(Using matlab language, for histogram analysis method can also be called a modal method)

循环自相关函数工具箱，还带有自己编写的代码，ex1-7．(Circulating auto-correlation function of the toolbox, but also prepared with its own code, ex1-7.)

基于matlab编程的叶片泵在过渡区中的卸压梯度曲线，卸压曲线。(Unloading pressure gradient curve of vane pump of MATLAB programming in the transition region based, unloading curve.)

tfsa的工具箱，包括了wvd一系列的时频域处理工具。使用方法，直接将该压缩包拷贝到任意目录，解压，使用matlab添加该路径就可以。(Tools to deal with non-stationary signal including a series of wvd. You can use it by uncompressing and including it in the matlab.)

以齿轮系统动力学和非线性动力学理论为基础,针对齿轮系统时变啮合刚度和齿侧间隙耦合作用的具体特点,建立了齿轮系统非线性模型,并用数值积分和数值仿真方法对其在某些参数域中进行了非线性振动研究(Based on the dynamics of a gear system and the theory of nonlinear dynamics, co nsidering characteristics of coupling action of the time-varying mesh stiffness and the gear backlash, a model of the nonlinear gear system is developed. The nonlinear vibration is studied by using numerical integration method and numerical simulation in some parameter fields.)

说明：  matlabBFGS程序 呵呵 呵额呵呵呵呵呵呵额(procedures matlabBFGS呵呵呵呵呵呵呵呵呵the amount of the amount of)

基于MATLAB软件，用计算曲线法来计算三相短路电流(Based on the MATLAB software, the calculated curve method can be used to calculate three phase short circuit current)
