用于三点定位的算法，是做声音定位可用的，希望有部分帮助，可适当运用(It is used to location the point you want.)

说明：  线弹性umat钛合金,有cae文件，可以进行晶体塑性模拟(linear umat for titanium aloy)

最速下降法就是梯度下降法,可以用于求解最小二乘问题(线性和非线性都可以)。可以说是求解机器算法的最古老、最经典的模型，另一种常用的方法是最小二乘法。(The steepest descent method is the gradient descent method, which can be used to solve the least squares problem (both linear and non-linear). It can be said that it is the oldest and most classical model for solving machine algorithm. Another commonly used method is the least square method.)

说明：  matlab调用cplex12.1的例子，这些例子对matlab的cplex接口函数做了非常详细的说明，适用于cplex-matlab的初学者(matlab call cplex12.1 the examples that the cplex interface function of matlab to do a very detailed explanation for beginners cplex-matlab)

该function文件可以利用二分法求解方程的数值解，其中有例子(The function files can be used to solve equations numerical solution of the dichotomy, of which examples)

说明：  此代码包括牛顿法和梯度下降法的实现过程，最优化以及算法中常见的问题解决方式(This code includes the process of Newton method and gradient descent method)

香农编码的C语言实现，VC++环境~~~~~~~~~~~~~~~~~~~~~~~~~(Shannon C-language coding, VC++ environment ~~~~~~~~~~~~~~~~~~~~~~~)

该程序是正定矩阵的Cholesky分解实例，Cholesky是矩阵分解常用的方法(The procedure is the Cholesky decomposition of positive definite matrix example, Cholesky matrix decomposition is a commonly used method)

nondominated sorting genetic algorithms，nsga2的c语言源代码，比较好。(nondominated sorting genetic algorithms，nsga2 c-language source code better.)

说明：  基于高斯赛德尔法的线性方程组解法（可消去系数矩阵病态）。基于牛顿法及改进的牛顿法实现对 非线性方程的求解。(Based Linear Equations high Sisaideer law (coefficient matrix can be eliminated morbid). Realization of nonlinear equations of Newton' s method for solving and improved Newton method is based.)
