function [a,b,err] = shanks(x,p,q) SHANKS Model a signal using Shanks method ---- Usage: [a,b,err] = shanks(x,p,q) The sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles. The modeling error is returned in err.

说明：  字典学习通过优化某个目标泛函, 由样本训 练出更适应于当前图像或者信号表示的自适应字典.(In dictionary learning, an adaptive dictionary which is more suitable for current image or signal representation is trained by optimizing a target function)

Convert a color image between color representations. B = COLORSPACE(S,A) converts the color representation of image A where S is a string specifying the conversion. S tells the source and destination color spaces, S = dest<-src , or alternatively, S = src->dest .
