用Matlab语言实现通信系统的后处理功能(Language communication system using Matlab post-processing functions)

Shapiro提出的内嵌零树小波编码算法(EZW Embedded Zerotree Wavelet),其出发点在于小波变换后各级子带系数之间在空间上和方向上所呈现出带间相似性,这种空间相似性可以用一种新型的数据结构--零树(Zerotree).EZW算法就是充分利用这种相似性,获得高性能的图像编码算法.(Shapiro' s embedded zero tree wavelet coding algorithm (EZW Embedded Zerotree Wavelet), whose starting point is at all levels of sub-band wavelet transform coefficients and the direction in space with the similarity between shows, this space can be similar with a new data structure- zero tree (Zerotree). EZW algorithm is to take full advantage of this similarity, access to high-performance image coding algorithms.)

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )
