系统仿真导论第一个实验程序，龙格库塔实验程序(Introduction The first experimental system simulation program, Runge-Kutta experimental procedures)

这是一段导线找形的命令流，可用于ansys有限元分析(This is a piece of wire to find the form of order flow, can be used for finite element analysis ansys)

说明：  你输入一个长方体的长和宽以及高，就可以输出他的面积(input height，width，length，output volume)

岩土数值模拟计算的程序，可以用来计算边坡、岩石稳定性。(Numerical simulation of geotechnical calculation program can be used to calculate the slope, rock stability.)

用于计算大物实验中常用的平均值和不确定度。(a simple tool to calculate average of input values.)

单元刚度矩阵，用于计算三单元刚度矩阵，输出刚度矩阵(Element stiffness matrix is ​ ​ used to calculate the three-element stiffness matrix, the output stiffness matrix)

傅立叶变换的C语言实现，可在Turbo C以及Visual C++下实现。(Fourier Transform C language, in Turbo C and Visual C under.)

this source code is use to calculate resister capacitor and inductor

说明：  这是一个ACM试题中的算法，叫分而治之算法，上面有PPT还有实例代码，希望喜欢ACM的同学可以喜欢(This is a Question in the ACM algorithm, called divide and conquer algorithms, there are examples of the code above, there are PPT hope that students like to be like the ACM)

说明：  研究舍入误差的例程，可以帮助初学计算方法的人。(Of rounding error in the routine that can help beginners who calculation.)
