适用于ABAQUS的自定义材料子程序，适用于平面单元的随动强化J2模型。(Applies the custom material subroutine in ABAQUS, kinematic hardening J2 model applies to plane unit.)

预估校正法，关于解分数阶微分方程的算法程序，适合非线性方程(Solves an initial value problem for a non-linear differential equation of fractional order (FDE). The code implements the predictor-corrector PECE method of Adams-Bashforth-Moulton )

这是利用C++ 编的fft(This is the C series fft)

A FORTRAN IV function to compute the probability of a standard normal deviate

EKF uKF的matlab工具箱，适合做非线性滤波的仿真计算。(EKF uKF the matlab toolbox for nonlinear filter to do the simulation.)

采用随机数产生2到10阶的随机矩阵，并实现了矩阵的相关运算，比如：加减，乘除，求逆，求行列式(Using random Numbers generated random matrix from 2 to 10 order , and achieving relative to the implementation of the matrix operations, such as: add and subtract, multiple and divided, inverse and determinant)

说明：  编程观察无穷级数 1/n的收敛性。 采用 IEEE 单精度浮点数，观察当 n 为何值时求和结果不再变化，将它与理论分析的结论进 行比较 (注：在 MATLAB 中可用 single 命令将变量转成单精度浮点数)。(Programming observation of convergence of infinite series 1/n)

非线性方程数值解法的数学基础，有牛顿法，割线法等(Mathematical foundations of numerical solution of nonlinear equations, Newton method, secant method)

牛顿迭代求根法和牛顿-steffensen加速法(Newton method for root-solving problems. Newton-Steffenson is also included.)
