葛哲学编著《小波分析理论与MATLABR2007实现》的所有源代码·包含大量的实例和典型应用(some refer for lisp)

说明：  《AutoLISP 机械设计高级应用实例》 基于autolisp和CAD的机械绘图方面的专业书籍(AutoLISP Advanced Application Examples of Mechanical Design Professional Books on Mechanical Drawing Based on Autolisp and CAD)

运用谱聚类的方法（如Ncuts和NJW的算法）结合kmeans进行了数据的聚类分析(Using the method of spectral clustering algorithm (such as Ncuts and NJW) combined with kmeans clustering analyzed)

框选成角平行墙体线，倒角。 用于封闭因有窗体截断墙体线，不能计算墙体工程量，可删除墙体封口线，并对墙体线倒角。 (The frame chooses the angle parallel wall line, the bevel edge. Because uses in sealing up has the window to interrupt the wall line, cannot calculate the wall resilience, may delete the wall seal line, and to wall line bevel edge.)
