Restruction from single branch from two dimension multiple level decompstion
X=wrcoef2(type,c,s,wname,[N]) X=wrcoef2(type,c,s,Lo_R,Hi_R,[N])
wrcoef2 is for reconstruciton from single branch of two dimension multiple level decompostion. Extension mode is stored as a global variable and could be changed with dwtmode. If N is omitted, maximum level is used.
x=rand(100,100); [C,S]=wavedec2(x,3,'db2'); A2=wrcoef2('a',C,S,'db2',2); | ![]() | ![]() |
