一款很好用的卫星重力异常布格校正Fortran90程序。(A very useful bouguer correction Fortran 90 program。)

nsolgm 算法 是求解非线性方程组的一种非常有效而且又快捷的方法(nsolgm algorithm for solving nonlinear equations is a very effective and efficient way and)

说明：  MATLAB在线性代数中的一些基本操作，比如矩阵相加等等。(Basic operation of linear algebra)

abaqus drucker-prager UMAT字程序(abaqus drucker-prager UMAT subroutine)

说明：  利用matlab实现的部分CFD功能的代码，很有参考价值(Matlab to achieve part of the CFD function of the code, a very valuable reference)

说明：  常用于分析降水、径流、气温等要素时间序列的趋势变化，其优点在于样本不需要遵循某一特定的分布，而且很少受到异常值的的干扰，计算简便。(It is often used to analyze the trend change of time series of factors such as precipitation, runoff and air temperature. Its advantage is that the sample does not need to follow a specific distribution, and is rarely disturbed by outliers, so it is easy to calculate.)

SPH方法计算二维溃坝问题的源程序，个人觉得还可以(Two-dimensional dam break problem SPH method the source, individuals felt that I could)

一个有限元计算的例子,初学者可以参考，简单易看懂(an example of FEm computation)
