Fortrann 77的集成 开发环境，可以在 IDE的环境下编辑、 编译、运行源程序(Fortrann 77 integrated development environment, IDE environment editing, compiling, running source)

铁木辛柯梁梁单元有限元程序，可以自动形成刚度阵，质量矩阵(Ironwood oct Ke Liangliang unit finite element program can automatically form stiffness matrix, mass matrix)

分析两时间序列之间的超前和之后关系，计算滞时长度，多用于水文气象方面分析研究(Analysis ahead of and after the relationship between the two time series, calculating the lag length, used for the analysis of hydrometeorological)

该程序为全向比幅法测角程序，并给出了测角误差分析(The program is omnidirectional amplitude ratio angle measuring program, and the angle error analysis is given)

全局最优化方法的程序，是段老师团队原版程序，大家放心使用。(Global optimization method of procedure is the original section of the teacher team program, we ease of use.)

1. 牛顿迭代法 function [x,i]=newtonmethod(x0,f,ep,Nmax) 牛顿法求非线性方程根 x0是输入初始值, f是输入函数, 精度要求ep, Nmax为最大迭代次数 x是输出迭代序列,i是迭代次数 2. 二分法 function [x,k]=bisection(a,b,f,ep) 二分法解非线性方程 输入区间[a,b],函数f和误差ep, Nmax为最大二分次数 x为输出近似根, k为二分次数 ( Newton s law and the dichotomy)

计算多项流的好程序，简单好用，计算量小。可以较好的模拟二维的两项变化情况(Calculating a number of streams of the program, easy to use, small amount of calculation. Can better simulate the two-dimensional variation)

说明：  设计一个函数，其功能是同时求得长度为20的整型数组所有元素中的最大值、最小值和平均值。并用相应的主函数对其进行测试，测试数组可以用随机数填充或者自行定义数据。(The design of a function, its function is to obtain the length of the maximum, minimum and average 20 integer array element. And its main function testing, the test array can be populated with a random number or define your own data.)

谐波分析，加窗fft插值算法，幅值校正；多次谐波；峰值搜寻(Harmonic analysis；fft)

说明：  平面问题的有限元基础，大家可以参考一下学习学习(The finite element foundation of the plane problem, you can refer to it)
