时域差分法计算一维光子晶体反射率和透射率。时域差分法是最新研究光子晶体的科学数值方法。使用MATLAB编写了其源码，对于研究光子晶体的人们，有重要参考价值。

给出集合类的定义，可模拟实现集合的交集，并集运算，并可以插入，删除元素-is set class definition can be simulated to achieve the intersection and set computing, and can be inserted, deleted elements

非线性规划是20世纪50年代开始形成的一门新兴学科。1951年HW-Kuhn和AW-Tucker发表的最优性条件（后称Kuhn-Tucker条件）是非线性规划论文正式诞生的重要标志；

计算力学编程,有限元-computational mechanics programming, finite element

这是一个利用数值算法中三次样条插值方法。编译的人口普查问题。供个高校有关专业参考-This is a numerical algorithm using cubic spline interpolation method. Compiling the census issue. For the professional colleges reference

研究生期间上《数值计算方法》课的作业，所有代码都是C语言实现并调试通过，现在上传为大家服务。这是Jacobi算法-Jacobi algorithm with C language

初学者实现矩阵乘法，觉得矩阵乘法简单但很实用，写的不是很高效，可以下载下来研究研究哦。-beginners achieve matrix multiplication, a simple matrix multiplication think it is practical and writing is not very efficient and can be downloaded from studies oh.

求解一维非稳态导热扩散方程的C语言程序，分别考虑三种不同边界条件，采用TDMA算法求解三对角矩阵-Calculation of heat transfer analysis one-dimensional diffusion equation

A program for solving equations using Newton s Method.Just need to modify the data in the main function. If there is any bugs, please contact chenxiang@cad.zju.edu.cn

This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.-This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages.
