说明：  用fortran 70实现数值积分，并实例计算了三个函数，导出了积分值和误差(The numerical integration is realized by FORTRAN 70, and three functions are calculated with examples. The integral values and errors are derived.)

《数字信号处理》一书讨论的内容，主要是离散时间信号的博氏变换和数字滤旋器，本书在该书内容的基础上，介绍了不再属于傅盟叶变换家族的另一种重要的变换一一希尔伯特变换。( Digital Signal Processing to discuss the contents of the book, mainly discrete-time signals and digital transformation Borrelia spin filter, and the contents of this book in the book, based on the introduction of the AU is no longer a Fourier transform Fu family, another important Hilbert transform 11.)

包含了悉尼科技大学徐亦达老师的课程课件，有贝叶斯理论、EM算法、卡尔曼滤波、HMM、粒子滤波、概率论相关知识等(The file includes knowledge about EM, HMM, particle filter, kalman filter and so on.)

计算半方差，如果按克里金法计算插值要求计算半方差，用此程序可实现。(Calculation of semi-variance, if the Kriging interpolation method call for the calculation of semi-variance, using this procedure can be realized.)

使用拉格朗日乘子法解约束优化问题，例子是最优化问题，有3个线性约束(Using the Lagrange multiplier method to solve the constrained optimization problem)

最新版的oofem 可以自己加入一些材料模型 版本更新速度也算快(latest version of oofem )

利用AR模型进行时间序列预测的程序源代码，使用最小二乘估计法进行参数估计。拟合效果非常好。(use AR model for time series prediction of the source code, the use of least squares estimation method to estimate parameters. Fitting very good results.)

根据输入的长宽，计算Rectangle面积周长等功能，并画出在txt文件中(Rectangle Create a class Rectangle with attributes length and width, each of which defaults to 1 a. Provide member functions that calculate the perimeter and the area of the rectangle. b. Also provide set and get functions for the length and width attributes. The set functions should verify that length and width are each integer numbers larger than 0 and less than 20. c. Write draw function to display the Rectangle: in Assignment1. ) d. Write a driver program to test class Rectangle.)

利用这个方法计算混沌时间序列的平均轨道周期p(Use this method to calculate the average orbital period of chaotic time series p)
