韶山电力机车三段桥在电感情况下波形三段桥仿真波形，电动机等效为电感，反电动势(Shaoshan electric locomotive segment bridge waveform in the inductive case of the three sections of the bridge simulation waveform, the motor equivalent inductance, back electromotive force)

LS-DYNA动力学分析，主要适用于显式动力学分析，本程序主要是K文件，希望能给大家了解一点如何修改K文件。(LS-DYNA dynamics analysis, mainly applied in the explicit dynamics analysis, this procedure is mainly K file, I hope everyone can understand a little how to modify the K file.)

维纳滤波其设计，假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。(Wiener filter is designed, assuming a point target in the x, y plane around the unit circle in a circular motion due to external interference, its trajectory shift occurred. Which, x the direction of the interference of mean 0 and variance of 0.05 Gaussian noise y direction of the disturbance is zero mean Gaussian noise variance 0.06.)

语音信号处理的端点检测程序，在编程中调用，很实用，值得你一看。(Endpoint detection)

feature extraction on faulty data

根据Zeller公式计算任意日期是星期几。说明一下，压缩包中有两个是复件，是用来压仓的，以确保满足上传条件（上传文件大于1K）。(weekday for any day)

说明：  有用的MATLAB 数字图像处理说明 有兴趣看看(MATLAB useful digital image processing that will look with interest at)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)

vc和matlab的混合编程，很好很全的(vc and matlab programming mix, full of very good)
