一个线性调频的信号仿真程序，大家试一试吧(A linear FM signal simulation program, we try it)

指数Milstein 方法解非线性随机微分方程，考虑其收敛阶。(the convergence of exponential Milstein method to nonlinear stochastic differential equations, )

后向差分法求解分数阶方程，源程序，现在日趋火爆，有学术价值(backward difference method to solve fractional derivation equation)

在分析结构损伤后，给结构添加噪声，再对结构不同损伤情况下的分析(After the analysis of structural damage to the structure adding noise, and then the structure is different in case of damage)

光伏并网逆变系统电流电压双闭环控制，测试成功，绝对可用！(Photovoltaic inverter current and voltage double-loop control system, the test is successful, absolutely free!)

Partition index is a measure ofvalidity similar to partition coeGcient, based on using Pj = ci=1 (uij)m as a measure ofhow well the jth data point has been classi- 2ed. The closer a pixel is to a codebook entry, the closer Pj is to one. Ifa pixel becomes an outlier to all cluster centers, the value of Pj approaches 1=cm − 1, which is the minimum value it can have.

说明：  MATLAB源程序代码分享：MATLAB实现组对象的整体几何变换(Matlab Source Code Sharing: Matlab Group object to achieve the overall geometric transformation)

二维经验模态分解，采用形态学求极值点，径向基神经网络拟合，速度较快。(Two-dimensional empirical mode decomposition, the use of morphology for extreme points, Radial Basis Function Neural Network Fitting, faster.)

用MATLAB求Hu矩，并且可以求得一系列图像的Hu矩平均值(Hu moments with MATLAB demand, and can be obtained by a series of images of Hu moments mean)
