C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)

用matlab来模拟温度场，准确度高，具有参考价值。(yong matlab lai moni wenduchang ,zhuquedugao ,juou cankaojiazhi .)

用C语言程序通过先随机选取K个对象作为初始的聚类中心。然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。一旦全部对象都被分配了，每个聚类的聚类中心会根据聚类中现有的对象被重新计算。(C Programming Language by first randomly selected the K object as initial cluster centers. And then calculate the distance between each object and each seed cluster center, and assign each object to its nearest cluster center. Cluster centers, and the object assigned to them on behalf of a clustering. Once all the objects are assigned to each cluster cluster centers will be based on the existing object clustering is recalculated.)

二维贴体网格 fortran 源程序；偏微分方程生成网格，附详细的说明文档(body-fit mesh generation, two dimension)

说明：  本程序是采用FDTD算法结合PML吸收边界，对对称三层平板光波导的模式场仿真(This program uses FDTD algorithm and PML absorbing boundary to simulate the mode field of symmetrical three-layer planar optical waveguide.)

将字符串合并的时候要注意中间的空格，否则可能在合并时出错。我调试了好久才发现(combine the string,essential to focus the length of string)

此程序为基于时域有限差分法的matlab程序，主要是计算二维MUR吸收方柱散射(This procedure is based on finite difference time domain method matlab program, mainly of two-dimensional scattering MUR absorbing square columns)

该程序用来对多种物质混合物吸收光谱数据进行分析，拟合出光谱曲线并且得到其各个峰值位置所在。(The program is used for a variety of mixtures of substances absorption spectral data analysis, curve fitting, and by their spectral location of each peak.)

Dr. Liu 在《光滑粒子流体动力学--一种无网格方法》一书中提供的光滑粒子流体动力学（SPH）源程序，采用Fortran语言编写，用于计算可压缩流体力学问题。(Dr. Liu in the " Smooth Particle Hydrodynamics- a meshless method," a book provided by the smooth particle hydrodynamics (SPH) source code, using Fortran language, used to calculate the fluid flow problem.)

说明：  运用固定点算法实现快速的独立成分分析，实现代码为matlab(use of the fixed-point algorithms to achieve rapid Independent Component Analysis, to achieve code-Matlab)
