％1998年全国大学生数学建模竞赛A题：收益与风险 模型求解

求函数极小值，适用于不带约束的、函数可以为非线性的无约束规划问题的求解-Demand function is minimum applicable to non-binding, the function can be non-binding for the non-linear programming problem solving

空间八节点实体单元的有限元三维计算程序,通用性较好-Eight-node solid element space of three-dimensional finite element program, GM is better

非常好的插值程序-very good interpolation procedures

该算法实现了QPSK调制解调，载波同步算法采用costas环，位定时采用Gardner算法

本程序使用forten编写的，内容详细,可运行得到反演结果，解压后，主要程序在名为src的文件夹中，正演部分采用交错网格有限差分法，反演基于共轭梯度实现

哈夫曼编码构造 c++程序 -Huffman coding structure c procedures

一个关于傅里叶变换的程序，可以从桌面读入文本-One on the Fourier transform of the program, you can read text from your desktop

大学C语言作业练习，求解一个数是否是素数，通过运行程序，输入一个数字，程序将自动判断这个数是否为素数。给出相应的结果。

目前的商用有限元程序不但分析功能几乎覆盖了所有的工程领域，其程序使用也非常方便，只要有一定基础的工程师都可以在不长的时间内分析实际工程项目，这就是它能被迅速推广的主要原因之一。-The current commercial finite element analysis capabilities will not only cover almost all the engineering fields, and the procedure is also very easy to use, as long as there is some basis for engineers can be a long period of time without an analysis of actual projects, that is, it can be rapidly expanded one of the main.

在Turbo C环境下开发，实现对称矩阵的输入，并判定是否为正定。可以修改输入模块实现对任意非奇异矩阵求逆。求逆算法采用伴随矩阵法，求解行列式采用化上三角矩阵法。该算法系本人根据《线性代数》描述编写，矩阵的最大阶数可任意修改，更具有通用性。-in Turbo C development environment and achieve symmetric matrix input, and to determine whether the positive. Can modify the input module of arbitrary non-singular matrix inversion. Inverse algorithm adjoint matrix method, used to solve determinant of the upper triangular matrix. The algorithm is based on my "Linear Algebra" to describe the preparation, the biggest band Matrix will be able to arbitrarily amend, more versatile.
