绘制庞加莱截面图 在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

sobel和prewitt測邊的相關做法，sobel是一種high pass 處理，可將圖中的輪廓顯示出來(sobel edge measurement and prewitt related practices, sobel is a high pass processing, the outline of the figure can be displayed)

matlab宝典，matlab经典教材，讲解深入透彻；PDF文件，文字和图片都非常清晰，并有索引。(Collection matlab, matlab classic text, explain the depth and thorough PDF files, text and pictures are very clear, and index.)

说明：  比较详细介绍了matlab编程的语句，特别适合于初学者，是英文书籍，比较不错(matlab the language of technical computing)

模糊C均值聚类（FCM），即众所周知的模糊ISODATA，是用隶属度确定每个数据点属于某个聚类的程度的一种聚类算法。(Fuzzy C means clustering (FCM), known as fuzzy ISODATA, is used to determine membership of each data point belongs to a cluster of a clustering algorithm level.)
