用fortran编写的椭圆方程的数值算法

这是一个用java高级编程语言编写的程序，实现了用“向上/向下修正方法”的拉格朗日插值公式计算某个函数的值，方便实用。-Java This is a high-level programming languages used in the preparation of procedures, implementation of the " up/down correction method," Lagrange interpolation formula of the value of a function, convenient and practical.

我这是割线法和改进的欧拉法的源代码-This a secant method and improve the Eulerian method of source code!

单位长度为一。内外壁分别维持450度和50度。管道热导率1.05W/(m.k),求每米长管道热损失。

轮廓提取以后，实现了对轮廓点集之间的关系描述，使轮廓查找更容易，也便于对轮廓的后续处理，分析。

GUASS算法的列主元消去法-GUASS algorithm out PCA Elimination

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
