有限元法利用铁摩辛柯梁计算转轴质量刚度阻尼矩阵(Finite element method using the Timoshenko beam to calculate the stiffness and damping matrix of the shaft quality)

说明：  MATLAB实现自定义的拉格朗日插值和牛顿插值，均包括主调函数和被调用函数，程序简单易懂。(MATLAB realizes the self defined Lagrange interpolation and Newton interpolation, both including the main function and the called function, the program is simple and easy to understand.)

稀疏脉冲反褶积代码,包括高尔消元法解矩阵方程阻,自相关,互相关,褶积,反褶积的代码. 刚参加工作那会儿,上进心也足,爱动脑,编了很多的程序,唯有这一个是我引以为傲的,花了几个星期写的稀疏脉冲(预测)反褶积的代码,放到了现在,觉得也没必要再私藏下去了,不出五年,我都不知道这段代码是干什么的了. 希望对大家有用,方法太简单,所以效果不是太好,请大家修改,如要转载,请记得注明出处. (vc++)

模拟二维BZ反应扩散模型，方法是用显式EULER法求解模型的偏微分方程组(Simulated two-dimensional BZ reaction-diffusion model, the method is to use explicit EULER method for solving partial differential equations model)

判断点和线段之间的关系，包括点在线段的上，点在线段的延长线，反向延长线，点在线段外四种情况(Judge the relationship between the point and line, including the point on the line, in line at the extension of reverse extension cord, and so on.)

应用FORTRAN语言编写的通过方向应力张量与应力余弦张量求解主应力矩阵(Application FORTRAN language through direction cosine stress tensor and the stress tensor matrix solving the principal stress)

说明：  经过优化的C代码实现的Gauss-Seidel 迭代算法(Optimized C code of the Gauss-Seidel iterative algorithm)

偏最小二乘回归在matlap中的实现，源代码，有交叉效应(The implementation of partial least squares regression in matlap, source code, cross effect)

惩罚函数法C语言相关程序 它将有约束最优化问题转化为求解无约束最优化问题：其中M为足够大的正数， 起"惩罚"作用， 称之为罚因子，F(x, M )称为罚函数。(Penalty Function Method C language-related program it would have constrained optimization problem is transformed into solving unconstrained optimization problem: where M is a sufficiently large positive number, from the " punishment" effect, called the penalty factor, F (x, M) called the penalty function.)

说明：  含随机出题（四则运算）及其迭代程序、返回数组中最大子数组和及其迭代程序等。(Software class operations, including four operations and iterative procedure, returns an array of sub-arrays and the largest and Iterative procedures)
