图像插值程序，可以对图像任意缩放。例如：可以将大小为256 （高）×256（宽）的图像改变为大小为360×300的图像。-image interpolation procedures, the images can be arbitrary scaling. For example : can be the size of 256 (H) x 256 (W) to change the image size of 360 x 300 images.

使用C#编写，在一个画图面板 上通过绘制控制点来得到NURBS曲线，并可以对曲线进行平移、缩放、旋转等操作。

先准备好MFC DLL，打开VC 6.0=gt；文件=gt；新建=gt；项目=gt；MFC AppWizzard（DLL），项目名Calc=gt；下一步=gt；完成。好吧，你在文件视图上打开工作区可以看到有Calc.h，计算cpp，stdafx.h，stdafx.cpp文件那四份文件。

用matlab编写的，有限元三维梁单元的单元刚度矩阵计算程序，各节点6个自由度。-prepared by the three-dimensional finite element beam element of the element stiffness matrix calculation program, the 6-DOF nodes.

基于matlab平台，对1987年美国国会的投票情况进行数据补齐，根据投票情况区分议员党派。

用C语言表述图的数据结构，该图为有向图，且是用邻接矩阵表示的，然后同过深度优先算法遍历图中的每个节点，实现对其的访问。该程序描述的是关于数据结构中有向图的遍历操作，是对图这种数据结构的一种基本的访问方法。

This a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functions. The code consists of three simple classes: 1) Calc - which does the main calculations, 2) Stack - which is used to push and pop intermediate operators and numbers and 3) Symbol Table. The symbol table is a collection of calc symbols, a type structure consisting of various elements, including the expression name, function name, and the final value of the expression The evaluation procedure is done in three steps: 1) simplify the expression by removing all the elements within () and storing them in subexpressions within the symbol table. 2) Each of these sub expressions are then converted to RPN format (Reverse polar notation) and evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functi
