利用Matlab程序，绘制磁力线，采用三维作图，做出了长方体状磁体的磁力线分布(Matlab program used to draw the magnetic field lines, using three-dimensional mapping, rectangular-shaped magnets made of the distribution of magnetic field lines)

Fuzzy c-means clustering (FCM) with spatial constraints (FCM_S) is an effective algorithm suitable for image segmentation. Its effectiveness contributes not only to introduction of fuzziness for belongingness of each pixel but also to exploitation of spatial contextual information. Although the contextual information can raise its insensitivity to noise to some extent, FCM_S (1) still lacks enough robustness to noise and outliers and (2) is not suitable for revealing non-Euclidean structure of the input data due to the use of Euclidean distance (L2 norm).

In computer science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality.

matlab从入门到精通，想学matlab的朋友可以下载下来参考(matlab from entry to the proficient, want to learn matlab friends can download reference)

有关matlab pid仿真方面的pdf文档，很有参考价值，大家分享！！！！(papers about matlab PID!!!!!!!!!)

该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.(The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero.)
