displaying co-efficient

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

[Wayne King]

I have no idea what j,p,d1, and d2 are. Are they scalars?

[kash]

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

[kash]

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
