XP下的MPICH1.2.5软件包，用来做并行计算的最好开发环境！-the mpich1.2.5 softpack in xp system is the best develope enviroment for parallel computing

Fortran code to solve wave equation with multiple methods

该程序使用C++语言，实现分类，优点是使用SVM训练模型，简单、实用、可以实现二分类、多分类的功能

利用Gauss两点积分公式，进行数值积分的求解，并看它所具有的精确度。-The use of two points Gauss formula for numerical integration of the solution and see its precision.

该代码是在matlab编写的，主要用于求解线性规划问题-The code is written in matlab, mainly for solving linear programming problems

误差分析的方法有多种，这是一种先验估计误差的方法，较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果，以而使矩阵的误差分析获得了突破性的进展，使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。特别值得一提的是，在工程技术界，经常使用几种不同的计算方法，甚至使用实验方法进行比较，从而确定计算结果的可靠性，这也是一种有效而实用的方法。-error analysis by a number of means, which is a priori estimation error method, compared to the previous "Forward Error Analysis" in the matrix calculation error into the homes a better estimate on the results of a matrix so the error analysis of a breakthrough in the progress, many with forward error analysis can be difficult to determine on the numerical method to achieve new progress. Particularly worth mentioning is that in the engineering technology sector, often use several different methods of calculation, or even the use of experimental methods, in order to determine the reliability of results, which is also an effective and practical method.

实际上，有3种不同的代码内部拉链。2用不同的方法迭代算法，和一个是斐波那契使用递归算法。一个斐波那契序列是简单的迭代递归问题的情况下，很容易理解。

LDL 分解源码。从文件输入数据，编译运行后结果输出在输出文件中。-LDL decomposition source. Import data from the document, compiled the results after the operation output in the output document.

Fortran 77采用固定格式，所有代码均用gfortran编译器和英特尔Fortran编译器进行测试。所有代码分为15类。它包括
