Calculate entropy number of array
Ent = CalcEntropy(object,ent[,par])
1-d or 2-d object
type of entropy to use: options are
-- Coifman-Wickerhauser
-- sum log(|th_i|)
-- sum |th_i|^p, 0 < p < 2, p = par
-- #>= eps, eps = par
-- sum min(th_i^2,eps^2), eps=par
-- sum th_i
-- SURE(Thresholding), thresh = par
extra parameter, depends on type of entropy
Entropy of object
It is traditional to normalize the object to norm 1 before calling this routine. This routine does NO pre-scaling.
