arma模型的matlab谱估计实现，较详细(arma model spectrum estimation matlab implementation)

ONDULEUR DE TENSION TRIPHASE IN THE ONE BLOCK

SIFT特征（Scale-invariant feature transform，尺度不变特征转换)是一种电脑视觉的算法用来侦测与描述影像中的局部性特征，它在空间尺度中寻找极值点，并提取出其位置、尺度、旋转不变量(SIFT features (Scale-invariant feature transform, scale-invariant feature transform) is a computer vision algorithm to detect and describe the image characteristics of the locality, it scales in space to find extreme points, and extract its location , scale, rotation invariant)

1.Simulation of Electro-Optical Modulator 2.Generation of the Brillouin Profile 3.Simulation of BOTDR for strain in optical fiber sensors

High pass and low pass filters with matlab by using bode plot method. Showing very important thing is that bode plot does not give any information about transient response.

说明：  AR模型的大作业，涉及到2阶三阶四阶，估算AR模型的系数(AR model of operation, involving 2 third-order fourth-order, estimate the coefficient of AR model)

this file is usefull for fine alignement of 2 set of data

无线传感器网络DV-Hop节点定位算法，基于Matlab的源程序。(Wireless sensor network node, DV-Hop localization algorithm, based on the Matlab source code.)

说明：  说话人识别的matlab实现，供大家参考(tell the speaker s voice)

张正友平面标定法，基于matlab的文件文档(ZhangZhengYou plane calibration method, based on the matlab documentation )
