运用matlab进行模糊聚类分析步骤如下：建立数据矩阵；数据标准化；建立模糊相似矩阵；改造相似关系为等价关系；确定分类数(The steps of using MATLAB to carry out fuzzy clustering analysis are as follows: establishing data matrix; standardizing data; establishing fuzzy similarity matrix; transforming similarity relation into equivalent relation; determining classification number.)

说明：  梯度下降法对数据进行分类，并取了四个数据点，对分类进行证明。对梯度下降法有详细的备注。(The gradient descent method classifies the data and takes four data points to prove the classification. There are detailed remarks on gradient descent method.)

这是在matlab编程环境下，用小波变换实现的图像去噪处理程序。本程序可以直接加载电脑中的图片而不是使用matlab中自带的图像数据。适合小波变换去噪处理的初学者。(This is a programming environment in matlab, using wavelet transform for image denoising process. The computer program can load images directly instead of using image data that comes with matlab. Wavelet denoising for beginners.)

说明：  为ifft后的时域数据加cp的MATLAB程序。(After the time-domain data ifft added cp' s MATLAB.)

说明：  L-曲线法是反问题正则化方法中的参数选取中的重要方法，本程序给出了如何恰当选取其中的参数！(L-curve method is the inverse problem regularization method of parameter selection in an important way, this procedure is given on how to properly select one of the parameters!)

卫星轨道预测模型SGP的matlab源代码，经过了验证，可行！(SGP satellite orbit prediction model of the matlab source code, after verification, viable!)

matlab fem code is thr

possion方程的fem求解，生成刚度阵。欢迎提出宝贵意见。(fem for solving the possion equation ，stiffness matrix is generated. Welcome to give valuable advice.)

说明：  用于对高密度源数据进行预处理，将其转换为INV反演数据格式和便于suffur成图的数据格式。(used for high-density source data pretreatment and convert it to INV inversion data formats and facilitate suffur mapping data formats. )
