说明：  二维河道水动力模型；matlab 迭代程序；水质模拟(Two dimensional river hydrodynamic model; MATLAB iterative program; water quality simulation)

umat公式详细介绍，我也不知道够20字了mei(the introduction of umat in abaqus)

己知一些离散的点，使用matlab利用最小二乘法拟合(Had a number of discrete points, with linear least squares fitting)

正则化方法包括Tikhonov，tsvd,ttls,tgsvd,csvd(Regularization Method include Tikhonov，tsvd,ttls,tgsvd,csvd.)

基于Biegler动态优化正交配置法（联立算法）的matlab 代码，由M.Cizniar，M. Fikar等编写(dynopt is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimised, subject to equality and inequality constraints, using orthogonal collocation on fi nite elements method.)

用Fortran编写的非线性优化软件，具有一定的智能搜索功能(used in Fortran program)

说明：  模拟光子在多层组织中传输的蒙特卡洛仿真，包括散射系数，吸收系数，光场分布等特性(Monte Carlo simulation of photon propagation in multilayer structure ,It includes scattering coefficient, absorption coefficient,light field distribution and so on.)

This is a simple mergesort code. It contains four directory. In the "lib" directory, there re two source code that can serve as timer and memory usage indicater. In the "src" directory, function "mergesort" can perform merge sort, while there s also a main function to execute it.

最优化的bfgs算法，是采用matlab编程(BFGS optimization algorithm, using matlab programming)

说明：  有用的软件，用于高阶统计量计算。代码完整，计算效率高。(useful software for high-end statistical calculation. Code integrity, high computational efficiency.)
