用于学习LBM对流体的研究，可以加深对LBM的理解(LBM fluid)

使用matlab进行 有限元计算，内含多种方式方法，欢迎交流讨论(Finite element calculation using matlab)

很好的最小二乘求解工具，经典算法的c语言版本实现(A MINPACK-1 Least Squares Fitting Library in C)

复数的四则运算完整版，包括加减乘除，阶乘，开方等。。。(The plural arithmetic full version,, including addition, subtraction, multiplication, and division factorial, prescribing, etc...)

用吉尔方法积分一阶微分方程组的初值问题。(Gill method with integral equations of first order initial value problem.)

C#写的两个简单的小程序，分别用牛顿插值法和三次样条插值法来进行插值。(A program written by C#. It uses Newton Interpolation Method and Spline Interpolation Method )

说明：  levenberg-maquardt最小二乘拟合算法(This program do the levenberg-maquardt LS fit.)

本例是研究断裂问题的ABAQUS 子程序代码，使用Fortran语言编辑，研究扩展有限元的同志们可以借鉴一下。(This example is the study of fracture problems ABAQUS subroutine code, Fortran language editing, extended finite element study comrades can learn it.)

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)

根据给定的等距结点上的函数值与一阶导数值, 用埃尔米特等距插值公式计算指定插值点处的函数值。(According to the given equidistant nodes function value with a first derivative values, with equidistant interpolation Hermite interpolation formula specified function value at the point.)
