数字水印MATLAB编程中长用到的一些函数，Z字扫描和NC值计算，希望有帮助(MATLAB programming in digital watermarking used in some of the function of a long, Z word scan and NC values, hopes to help)

计算并显示半带滤波器,显示H0,H1,及 H0+H1的幅频响应(to design a CQMF filter)

three phases in Matlab

matlab程序画图，常见分形图，function cantor(A,B) c=1 p=0 figure hold on plot([A(2) B(2)],[A(1) B(1)], r* ) while norm(A(1,:)-B(1,:))>=1 C=[] D=[] for i=1:size(A,1) a=A(i,:)+(B(i,:)-A(i,:))/3 b=A(i,:)+2*(B(i,:)-A(i,:))/3 C=[C A(i,:) b] D=[D a B(i,:)] end A=C B=D p=p+1 (matlab program drawing, common fractal images function cantor(A,B) c=1 p=0 figure hold on plot([A(2) B(2)],[A(1) B(1)], r* ) while norm(A(1,:)-B(1,:))>=1 C=[] D=[] for i=1:size(A,1) a=A(i,:)+(B(i,:)-A(i,:))/3 b=A(i,:)+2*(B(i,:)-A(i,:))/3 C=[C A(i,:) b] D=[D a B(i,:)] end A=C B=D p=p+1 )

说明：  用S函数编写的量化器 量化步长为非线性 即 量化步长可调 (Prepared by S function to quantify the quantizer step size for the non-linear quantization step size that is adjustable)

PLS and PCA algorithms tool

Matlab程序，计算Bayliss分布天线方向图。(Matlab program that calculates Bayliss distributed antenna pattern.)

说明：  a text searching algorithm, still not completed but I will finish it soon.

说明：  可根据需要一步步生成三变量或者四变量的卡诺图！谢谢！(To make kanuotu!)

本文用1961-2006年广西88个气象观测站的各月雨量资料，北半球500百帕月平均高度场资料(576个格点)，国家气候中心提供的部分环流特征量资料，通过EOF分解、合成分析、S(A practical estimate on the credibility formula is presented, where a piecewise linear function is taken as the approximation of the prior distribution and applied to the credibility theory. The convergence of the approximation is analyzed.)
