非线性方程组求解

计算矢量拉盖尔高斯光束中古伊相移产生的角衍射，及其与能流分布的关系。(The Poynting vector)

典型的二维kalman滤波原理程序，容易掌握！(typical two-dimensional Kalman filtering process easy!)

This program is used to find the union, intersection and exclusive OR for given two sorted arrays.

包括基本的克里金(Kriging)插值法实现代码，仅实现基本方法部分，不包含扩展克里金方法( kriging uses ordinary kriging to interpolate a variable z measured at locations with the coordinates x and y at unsampled locations xi, yi. The function requires the variable vstruct that contains all necessary information on the variogram. vstruct is the forth output argument of the function variogramfit. This is a rudimentary, but easy to use function to perform a simple kriging interpolation. I call it rudimentary since it always includes ALL observations to estimate values at unsampled locations. This may not be necessary when sample locations are not within the autocorrelation range but would require something like a k nearest neighbor search algorithm or something similar. Thus, the algorithms works best for relatively small numbers of observations (100-500). For larger numbers of observations I recommend the use of GSTAT. Note that kriging fails if there are two or more observa)

截断奇异值分解技术是一种正则化方法，用于不适定问题的数值计算(Truncated Singular Value Decomposition is a regularizaiton method for ill-conditioned problem computation.)

线性方程组的计算，采用的是高斯消元法来实现的。只有主要的算法代码，没有写主函数(Calculation of linear equations using the Gauss elimination method to achieve. Only the main algorithm code, did not write the main function)

小波包分析提取振动信号中的特征频率，调试通过可以使用，自己编的5种调制信号。( Wavelet packet analysis to extract vibration signal characteristic frequency, Debugging can be used, Own five modulation signal.)

自己写的稀疏矩阵类，包括存储、访问以及基本的数学运算，希望大家批评指正！(Sparse matrix classes, including storage, access, and basic mathematical operations, we hope to criticism!)

使用Y矩阵来综合得到耦合矩阵M中各元素的matlab源代码(The Y matrix to obtain an integrated coupling matrix M of each element matlab source code)

自己编写的期望最大化（EM）算法的MATLAB实现，里面有较为运行方法和程序说明，对新手有很好的帮助( I have written the expectation-maximization (EM) algorithm in MATLAB, which has run more methods and procedures described, there is a good help for the novice)
