实现 NL_means 算法，用来去噪。并赋带使用例子和实验结果。(Achieve NL_means algorithm to de-noising. And endowed with the use of examples and experimental results.)

computes Input/output auto/cross-correlation.(computes Input/output auto/cross-corre IBM.)

说明：  可以对数量少、残缺、不完整的数据进行预测，如人口、缺水量等。也可以对灾害发生时间进行预测。(Can be a small number, mutilated, incomplete data to predict, such as population, water shortage and so on. You can also predict the time of occurrence of the disaster.)

说明：  %inverstable inverse_tb = gf(zeros(1, t+1), m); for i=1:t+1, inverse_tb(i) = alpha^(-i+1); end; %chien's search lambda_v = zero; accu_tb=gf(ones(1, t+1), m); for i=1:n, lambda_v=lambda*accu_tb'; accu_tb = accu_tb.*inverse_tb; if(lambda_v==zero) error(1,n-i+1)=1; else error(1,n-i+1)=0; end end found = find(error(1,:)~=0)

Interpolation refers to the process of converting a sampled digital signal (such as a sampled audio signal) to a higher sampling rate (Upsampling)
