Hello

I wrote this simple code

lev=8;			
wname='d8';

dec=dwt(ld, filter=wname, n.levels=lev, boundary="periodic", fast=TRUE);
i_ld=idwt(dec);


before
http://r.789695.n4.nabble.com/file/n2316043/1.png 1.png 
after
http://r.789695.n4.nabble.com/file/n2316043/2.png 2.png 

I don't uderstand why there is a difference  between signal befor dwt and
after idwt

thank you
