实现对地震数据的一维傅里叶变换 并对数据进行设定工业频率值的情况下滤波 (power frequency filtering)

说明：  EM 算法是Dempster，Laind，Rubin于1977年提出的求参数极大似然估计的一种方法，它可以从非完整数据集中对参数进行 MLE估计，是一种非常简单实用的学习算法。这种方法可以广泛地应用于处理缺损数据、截尾数据以及带有噪声等所谓的不完全数据，可以具体来说，我们可以利用EM算法来填充样本中的缺失数据、发现隐藏变量的值、估计HMM中的参数、估计有限混合分布中的参数以及可以进行无监督聚类等等。(EM algorithm is a method for maximum likelihood estimation of parameters proposed by Dempster, Laind and Rubin in 1977. It can estimate parameters from incomplete data sets by MLE. It is a very simple and practical learning algorithm. This method can be widely used in dealing with the so-called incomplete data such as defective data, censored data and noisy data. Specifically, we can use EM algorithm to fill missing data in samples, find hidden variable values, estimate parameters in HMM, estimate parameters in finite mixed distribution, and so on. Unsupervised clustering and so on.)

用于最大信噪比准则方向图和功率谱，自己编写，仅供参考(Pattern for maximum signal-to-noise ratio criterion and the power spectrum, write your own, for reference only)

此程序为地震数据处理中的反褶积，用于提高纵向分辨率。此程序构建在简单褶积模型上，分为脉冲和预测反褶积两种，参数可自调。(This procedure for seismic data processing deconvolution, used to improve the vertical resolution. This program is built on a simple convolution model is divided into pulses and predictive deconvolution two parameters can be self-adjusting.)

说明：  很好玩的，虽然简单一点，但是足可以说明混沌的出现的问题(is a lot of fun, though simple, but enough to note the emergence of a chaotic problems)

VLFEAT,一个强大的SIFT库函数,适合MATLAB和VC应用(VLFEAT, a powerful SIFT library functions for MATLAB and VC application)

最大似然（ML）准则和最大后验概率（MAP）准则，多机电力系统仿真及其潮流计算，采用的是脉冲对消法。( Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, Multi-machine power system simulation and flow calculation, It uses a pulse of consumer law.)

主成分分析的c++实现使用奇异值分解svd算法(Principal Component Analysis based on svd algorithm ，used c++)

定义一个结构体变量（包括年、月、日），计算该日在本年中为第几天？（注意考虑闰年问题），要求写一个函数days，实现上面的计算。由主函数将年月日传递给days函数，计算后将日子传递回主函数输出(Define a structure variable (including the year, month, day), calculated on that day in the middle of this year for the first few days? (Note that the leap to consider the issue), asked to write a function of days, to achieve the above calculations. By the main function will be passed to the days date function to calculate the days will pass back to the main function of the output)
