本文主要讨论获得图片后如何提取其边界信息，首先利用图像灰度均匀化解决了对比度不清晰的问题，然后利用高斯滤波法对图片进行滤波去噪，进而利用Canny算法实现边缘检测提取边界，该方法与Matlab自带的求边界方法有明显的提高，为利用Matlab程序求图像分形维数提供了更精确的前提。(This article focuses on how to get the image to extract the boundary information, the first to use to the gray uniform solve the contrast is not clear, and then use the Gaussian filter image filtering noise, and then use the Canny edge detection algorithm to extract the boundary of the and Matlab comes boundary method has increased significantly, and provide a more accurate premise for the use of Matlab program for image fractal dimension.)

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

simple code for rotating spinor in the bloch sphere . Not that great . Used quaternion to do the job.

在此做了一个小例子讲解matlab中主成分分析princomp.(例子是matlab自带,您也可以直接看matlab的帮助文件,此贴仅给菜鸟看,高手无需(Do a small example to explain this the matlab principal component analysis princomp. (Example matlab comes, you can directly see the matlab help files, glue only to the rookie see no need to master)
