本程序能够从图像中自动提取出椭圆，并且求出椭圆的参数方程(This procedure can be automatically extracted from the image of an oval, and elliptical to derive the parameters of equation)

说明：  采用matlab对两幅视差图像进行3维重建，利用了对极几何的关系。(Matlab on the two parallax images with a 3-dimensional reconstruction, use of a very geometric relationship.)

说明：  MATLAB在信号处理中的典型应用-MATLAB在傅里叶变换中的应用。(MATLAB in signal processing in a typical application-MATLAB in the Fourier transform applications.)

TOPS alg method for linear array

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.)

采用低通性质的平滑函数为高斯函数，根据他的一阶导数、二阶导数作为小波基函数进行突变点分析。 (The use of low-pass nature of the smoothing function for the Gaussian function, according to his first derivative, second derivative wavelet basis function as a point mutation analysis.)

Smooths a matrix (with/without NaN s) via recursive moving average method and eliminates data gaps. (MOVING_AVERAGE(X,F) smooths the vector data X with a boxcar window of size 2F+1, i.e., by means of averaging each element with the F elements at his right and the F elements at his left. The extreme elements are also averaged but with less data, obviously. Leaving the edges intact. The method is really fast. MOVING_AVERAGE2(X,M,N) smooths the matrix X with a boxcar window of size (2M+1)x(2N+1), i.e., by means of averaging each element with its surrounding elements that fits in the mentioned box centered on it. This one is also really fast. The elements at the edges are averaged too, but the corners are left intact. NANMOVING_AVERAGE(X,F) or NANMOVING_AVERAGE(X,F,1) accept NaN s elements in the vector X the latter interpolates also those NaN s elements surrounded by numeric elements. NANMOVING_AVERAGE2(X,M,N) or NANMOVING_AVERAGE2(X,M,N,1) accept elements NaN s in the matrix X the latter interpolates also those NaN elements surrounded by numeric elements.)

TDMS的文件读取到Matlab。 优点： -支持读取v2的文件 -不需要使用NI的DLL，因此它不需要32位窗口 - 支持隔行扫描数据 -只允许读的名称及属性，以得到一个文件是什么感觉快 - 允许读数据的特定子集 (Reads TDMS files into Matlab. Advantages: - supports reading v2 files - doesn t require the NI DLL, thus it doesn t require 32bit windows - supports interleaved data - allows only reading names & properties to get a quick feel for what is in the file - allows reading specific subsets of the data)
