Edit-error displaying the co-efficients

I have a code  for 3d dualtree

x=rand(64,64,16);
J=1
[Faf, Fsf] = FSfarras;
 [af, sf] = dualfilt1;
 w = dualtree3D(x, J, Faf, af);

I displayed

CA1=w{1,1}{1,1}{1,1};

CA2=w{1,1}{1,1}{1,2};

CA3=w{1,1}{1,1}{1,3};

i get size as 32x256,is this correct,pleas help
