matlab学习指南-编写与调用函数教程,非常实用!(matlab study guide- prepare and call the function tutorial, very useful!)

基于特征的影像匹配——SIFT Method!!! 相当经典,只不过是MatLab源码，希望有哪位高手能转换成VC++源码!(feature-based image matching-- physiology Method! ! ! Quite classic, MatLab is the only source, which experts hope will be converted into VC source!)

生成一个规则LDPC码的教研矩阵H，其行数(越大越好)为列数的一半，行重为6，列重为3，任意两行没有围长为4的圈 使用方法：H=HGrandom2(m,n)。m表示行数，n表示列数(rules of a generation of research LDPC matrix H, its (larger the better) half of the series, re-6, series of three, two arbitrary line is not girth of the ring used four methods : H = HGrandom2 (m, n). Said a few m, n Columns)

改进cholesky分解，在cholesky分解基础之上进行改进，不需要分解的矩阵正定条件(Improve the cholesky decomposition, cholesky decomposition in the basis for improvement, positive definite matrix conditions without decomposition)

用MATLAB计算正弦波的波形数据.并产生.H档案(Calculated using MATLAB sine wave of waveform data. And produce. H file)

用matlab绘制面积图的例子程序，还不错哦。(draw area plot using matlab)

绘出时域图，在时域上进行分析，提取时域特征值：绝对均值，标准差，有效值，方根幅值，波形指标等等，进行故障特征提取，识别故障(The time domain diagram is drawn and the time domain is analyzed. The time domain eigenvalues are extracted: absolute mean, standard deviation, effective value, square root amplitude, waveform index and so on. Fault feature extraction and fault identification are carried out.)

说明：  计算信号复杂度，复杂度高，继续分解，用在信号分解中(Computational complexity)

ufc无监督优化模糊聚类用于彩色图像分割(ufc Unsupervised Fuzzy Clustering for Color Image Segmentation)

对二维图片进行中心放大，能控制放大的倍数，采用最近邻法(enlarge pictures from the center of it，can control the index for enlargement)
