该工具包是适用于地震数据的时频分析的工具包，对地震数据处理人员非常有用.(The kit is suitable for time-frequency analysis of seismic data toolkit for seismic data processing staff is very useful.)

各种格式图像间的转换，图像的基本操作常用函数(Transition between images in various formats, the basic operation of common functions image)

这个matlab程序可以同时对图像做高斯滤波和中值滤波处理。(The matlab program can do Gaussian image filtering and median filtering.)

说明：  如果对实际工程结构作简化处理，建立其动力学模型，并确定系统的质量、刚度、阻尼参数，便可以用多种方法建立系统的动力微分方程。常用的方法有直接 法、影响系数法、拉格朗日法以及有限元法等。拉格朗日法是从能量的观点建立系统的动能T、势能U和功W之间的标量关系，是研究静、动力学问题的一种方法。如果在选定运动坐标以后，能够设法求得坐标相对应的质量矩阵和刚度矩阵，就可以用影响系数法建立多自由度系统运动微分方程[4]。本文采用拉格朗日法建立了1/4车辆几何模型。(If the actual engineering structure is simplified, its dynamic model is established, and the mass, stiffness and damping parameters of the system are determined, the dynamic differential equation of the system can be established by various methods. The commonly used methods are direct method, influence coefficient method, Lagrange method and finite element method. Lagrange method is a method to study the static and dynamic problems, which is to establish the scalar relation among kinetic energy t, potential energy u and work W from the point of view of energy. If the mass matrix and stiffness matrix corresponding to the coordinates can be obtained after the motion coordinates are selected, the differential equation of motion of the multi degree of freedom system can be established by the influence coefficient method [4]. In this paper, 1 / 4 vehicle geometry model is established by Lagrange method.)

实现滑动去趋势波动分析，程序内部有解释，在MDFA文件中可以改变相应的参数值，使结果更好。x中存放的是脑电信号，这里没有上传。可以根据需要，用这种方法处理不同数据。(Achieve sliding detrended fluctuation analysis, is explained within the program, the file can be changed in the MDFA the corresponding parameter values ​ ​ so that the results better. x is stored in the brain signal, there is no upload. As needed, using this method to deal with different data.)
