madhirar1988年的关于桩网复合地基模型的计算程序(madhirar1988 year on net composite pile foundation model calculation program)

Taup域的反射法正演MATLAB程序，还不错，希望大家下去看看！(Taup domain reflectometry forward MATLAB program, well, I hope you go to see!)

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)

利用增加一个角度来调整地球旋转的变化，利用这个参数，可以绘制看起来是旋转的地球(The use of an additional angle to adjust the changes in the Earth' s rotation, using this parameter, you can draw the Earth' s rotation appears to)

Ma tla b 是当今使用最为广泛的数学软件，它具有相当强大的数值计算、数据处理、系统 分析、图形显示、甚至符号运算功能，是一个完整的数学平台，但是它不能实现端口操作和 实时控制Borland C + +Builder是一种新颖的可视化编程语言，可方便实现交互界面、数据 采集和端口操作等，但是它在数值处理分析和算法工具等方面，效率远远低于Matlab语言(Ma tla b is the most widely used mathematical software, it is quite powerful numerical calculation, data processing, analysis, graphics, or even symbolic operation, is a complete mathematical platform However, it can not be achieved port operation and real-time control Borland C Builder is an innovative visualization programming language, will facilitate the realization of interactive interface, data acquisition and the port operation, However, in numerical analysis tools and algorithms, the efficiency is far below the Matlab)
