说明：  对于学习通信原理并且要求运用matlab仿真的学者来说是一本很好的书籍。(Communication Theory for the study and asked the scholars to use matlab simulation is a very good book.)

optics算法 [RD,CD,order]=optics(x,k)； Aim: Ordering objects of a data set to obtain the clustering structure Input: x - data set (m,n) m-objects 对象数, n-variables 变量数 k - number of objects in a neighborhood of the selected object(OPTICS Ordering Points To Identify the Clustering Structure)

信号分析与处理中的卷积，适用于合成地震记录(Signal analysis and processing of convolution, for synthetic seismograms)

matlab code for Hatch fill patterns plus Color & Invert

由于显卡或者显示器的原因会出现实际输出的图像在亮度上有偏差，而Gamma曲线矫正就是通过一定的方法来矫正图像的这种偏差的方法.(Or because of the graphics display image will appear in the actual brightness of the output deviation, the Gamma correction curve is corrected by a certain method to the method of this bias image.)

说明：  对400幅灰度图像用分块PCA的方法进行压缩，进行通信时只用传输主元和特征向量。其中，pcaxiefangcha.m用于图像压缩，imresume.m用于图像恢复和部分图像的显示，chaweight.m用于绘制特征值比重-主元个数关系图，crdraw.m用于绘制压缩比-主元个数关系图，psnrdraw.m用于绘制总误差PSNR-主元个数关系图，psnrlocation.m用于绘制单幅图像误差PSNR分布图。(On the 400 block with a gray image compression method of PCA, to communicate only the main elements and characteristics of transfer vectors. Which, pcaxiefangcha.m for image compression, imresume.m parts of the image for image restoration and display, chaweight.m characteristic value for the draw weight- the main element number diagram, crdraw.m used to draw the compression ratio- the primary element number diagram, psnrdraw.m used to draw the total number of errors PSNR-principal component diagram, psnrlocation.m PSNR used to draw a single image error distribution.)
