线宽计算，用matlab计算线宽。可以得到的值来分析和使用半导体激光器线宽的联系(linewidth calculator)

This directory contains code implementing the K-means algorithm. Source code may be found in KMEANS.CPP. Sample data isfound in KM2.DAT. The KMEANS program accepts input consisting of vectors and calculates the given number of cluster centers using the K-means algorithm. Output is directed to the screen. Usage for KMEANS is: KMEANS SOURCEFILE <enter> The format of the source file is: NPat - Number of patterns (int) SizeVect - Size of vector (int) NClust - Number of cluster centers(int) vect[1,1] ... vect[1,SizeVect] - vector 1 (real) vect[2,1] ... vect[2,SizeVect] - vector 2 (real) . . . . . . vect[NPat,1] ... vect[NClust,SizeVector] - vector N (real) To compile: ICC KMEANS.CPP <enter> (This directory contains code implementing the K-means algorithm.

数值分析中三次样条插值算法，运行稳定，并能画出最后的插值曲线(Numerical Analysis of cubic spline interpolation algorithm, running stability, and can draw the final curve interpolation)

三个MATLAB里实现傅里叶变换FFT的源程序代码，每种代码都进行了作图演示(Three in MATLAB source code to achieve Fourier Transform (FFT), each code have been mapped demo)

我自己用c语言写的64点基4FFT算法，在visual c++ 6.0环境下编译通过。同matlab结果一致。(My own use C language to write the 64 based 4FFT algorithm, in visual c++ 6 compiler environment through. Results consistent with matlab.)

此为基于图像配准的傅立叶变换源代码，已精心调试过，请放心使用.(This is the image registration based on the Fourier Transform source code, has been painstakingly debugging, please rest assured that use.)

求实对称矩阵的特征值特征向量，内有读入数据文件。(Realistic symmetric matrix eigenvalue eigenvector, there are read into the data file.)

说明：  一个简单的matlab程序，用于实现自回归AR模型。( U4E00 u4E2A u7B80 u5355 u7684matlab u7A0B u5E8F uFF0C u7528 u4E8E u5B9E u73B0 u81EA u56DE u5F52AR u6A21 u578B u3002)

本代码为《最优化理论与方法》书籍重的信赖域算法的代码，本代码中的目标函数和约束等初值可由需要进行改变，来得到所期望的计算(The code for the " optimization theory and method" heavy books trust region algorithm code, the code of the objective function and constraints may need to change the initial value to get the desired calculation)

计算分数阶微分方程lypunov指数，确定混沌系统的混沌状态。(Calculated fractional differential equations lypunov index to determine the chaotic state of the chaotic system.)
