i HAVE A CODE
x=imread('st.tif');
x=rgb2gray(x);
x=double(x);
[Faf, Fsf] = FSfarras;
[af, sf] = dualfilt1;
J = 4;
T = 10;
[r c ]=size(x)
w = dualtree2D(x,J,Faf,af)
if i multiply w with another matrix i get error ,if i use cell2mat function even then i get error
cell2mat(w)
??? Error using ==> cell2mat at 55
Cannot support cell arrays containing cell arrays or objects.
please help how to solve this ,struck here for a long

That is because w is a cell array of cell arrays.
For example:
x = rand(16);
J = 1;
[Faf, Fsf] = FSfarras;
[af, sf] = dualfilt1;
w = dualtree2D(x, J, Faf, af);
w{2}{1} gives you the approximation image at level 1, so you can do:
App = w{2}{1};
The above is matrix
To get the dual tree detail coefficients (H,V,D),enter:
Atreedetcoefs = w{1}{1};
Btreedetcoefs = w{1}{2};
The above are cell arrays of matrices, you can use cell2mat on Atreedetcoefs and Btreedetcoefs, but you have to be careful that you know how the H,V, and D matrices are concatenated.

thanks wayne in complex wavelet transform i get error as
Scalar cell array indices required in this assignment.
Error in ==> Untitled2 at 34
wf{j}{p}{d1}{d2)=V
can u tell why i get this error

I have no idea what j,p,d1, and d2 are. Are they scalars?
kash
kash 2012-3-8
for j=1:6 % number of stages
for p=1:2
for d1=1:2
for d2=1:3
wf{j}{p}{d1}{d2)=V
end
end
end
end

App = w{2}{1}
i performed some operationin App and have same size
if i do
A{2}{1}=App
i get as {1x2},but i need {1x2}{1x2}to perform idualtree please help
