光子晶体光纤计算中相对抽运频率和四波混频效率的关系，有MATLAB程序和图形。对研究光子晶体光纤有很大的帮助。(Calculation of photonic crystal fiber pumped in the relative frequency and four-wave mixing efficiency of the relationship between the procedures and have MATLAB graphics. The study of photonic crystal fiber has a great help.)

说明：  给定求解区间，用最小二乘法给出函数的零点，并给出迭代次数(Given the solution interval, the zeros of the function are given by the least square method, and the number of iterations is given.)

算术编码是用符号的概率和它的编码间隔两俩个基本参数来描述的。算术编码可以是静态的或是自适应的。(Arithmetic coding to both of two basic parameters to describe the probability of the symbol and its coding interval. Arithmetic coding can be static or adaptive.)

包括了一个二维的方柱FDTD散射程序，入射波为TM模式，方柱无限长，等效为二维问题(Includes a two-dimensional square cylinder scattering FDTD procedures, incident for TM mode, infinite square cylinder, equivalent to two-dimensional problem)

fsolve函数求非线性方程组数值解，已经验证其正确性。(fsolve function for the numerical solution of nonlinear equations)

FFT with fix point 2*N

计算同轴电缆的时域有限差分算法的matlab程序(Finite-difference time-domain algorithm matlab program calculated coaxial cable)

14节点牛拉算法计算潮流程序，用于电力系统的潮流计算程序，可以直接用于潮流计算，也可以用于学习潮流计算的流程和方法。(For power flow calculation program, can be used directly flow calculation can also be used to study flow calculation processes and methods.)

该文件是用matlab开发的图论分析工具箱， 里面有使用时的详细说明，pdf说明文档。 绝对实用对于图论的研究者(The document was developed with matlab graph theory analysis toolbox, which are used when a detailed explanation, pdf documentation. Absolutely useful for researchers in graph theory)

这是python一个数学计算库，非常有用，而且python在处理科学计算时经常会用到它(This is a mathematical calculation python library is very useful, but when dealing with scientific computing python often use it)
