abaqus Umat 计算复合材料的损伤问题，可以学习一下(abaqus umat subroutine for damage of the composite material)

包括广义互相关函数GCC时延估计，通过matlab代码，计算加权加速度。( Including the generalized cross-correlation function GCC time delay estimation, By matlab code, Weighted acceleration.)

自己实现的一个简单的计算器，支持大数的加减乘除、开平方等操作，不适用库函数。(Themselves to achieve a simple calculator, to support the addition and subtraction, multiplication and division of large numbers, such as square root operations, library functions do not apply.)

CHEMKIN 2 源代码，使用Fortran语言编写，需要的可以下载(CHEMKIN 2 source code, written in Fortran, need can be downloaded)

说明：  积分公式(用锲比雪夫多项式构造积分点公式)(integral formula(using the Cheb. polynomial integral point) )

线性规划中的单纯形法的c实现，代码有测试类，(Simplex method for linear programming)

最小二乘法和支持向量回归机相结合无线传感网络节点定位的源码.(The source of The least squares and support vector regression combining wireless sensor network node positioning . )

应用遗传算法做电网规划，把遗传算法应用于输电网络规划，提出了基于遗传算 法的输电网络规划模型，以新建线路的投资费用和系统年运 行费用之和最小为目标函数，建立了输电网络规划的数学模型。该模型还考虑了“N-1”事故检验，使得规划方案更加合理。以Garver-6节点系统为例进行优化规划(The application of genetic algorithms to do network planning)

Delphi实现最小二乘法，进行多点拟合，目前支持4点拟合(Delphi realizes the least square method and multi-point fitting. At present, it supports four-point fitting.)

利用最小二乘支持向量机原理，创建了LSSVM预测模型(The principle of least squares support vector machine, created LSSVM prediction model)
