梁的有限元开裂分析代码，包括不同的裂纹形式，裂纹数目等(Finite element analysis of beams cracking the code, including different forms of crack, crack number, etc.)

计算给定序列的沃什(Walsh)变换序列。(Calculation of a given sequence of Vas (Walsh) transform sequence.)

本代码为《最优化理论与方法》书籍重的信赖域算法的代码，本代码中的目标函数和约束等初值可由需要进行改变，来得到所期望的计算(The code for the " optimization theory and method" heavy books trust region algorithm code, the code of the objective function and constraints may need to change the initial value to get the desired calculation)

给定样本点，采用高斯核密度估计，求出概率密度分布函数。(It is good to use this method to evaluate pdf)

最小二乘法在二维平面测向交叉定位里的应用(The least squares method in the two-dimensional plane measured to cross positioning)

说明：  矩阵求逆，使用fortran语言编写，希望能对有需要的朋友有所帮助(Matrix inversion, written in FORTRAN language, hoping to help friends in need)

Fortran编的关于分子动力学模拟的程序(Fortran programs compiled on the molecular dynamics simulations)

说明：  对该模型参数辨识采用递推最小二乘法，即 RLS（ recurisive least square）， 它是一种能够对模型参数进行在线实时估计的辨识方法。(The recursive least square method is used to identify the parameters of the model, that is, rls (recurisive least square), which is an online real-time estimation method for the model parameters)

计算方法：主要是高斯消去法的C语言算法实现(Calculation method: Gaussian elimination)
