How can I use squeeze to extract a 2D matrix with each point (x,y) having 3 items a,b,c?

Hello everyone, I need your assistance regard using squeeze to extract 2D matrix data. I will like to extract individually the value of w=1,2,3 OR at least all w together. Will really appreciate your assistance. Something like:

for v = 1:v_final
  for m = 1:m_final
     for k = 1:3
       w1=myval{v,m}(:,:,1);
       w2=myval{v,m}(:,:,2);
       w3=myval{v,m}(:,:,3);
      end
   end
end

I'm not sure why squeeze() would be involved and, since you already have a posted solution, I'm not sure what's different between that and what you're actually looking for. However, if all arrays myval{v,m} are the same size MxNx3, I would consolidate them into a 5-D array.

   W=cat(4, myval{:});
    W=reshape(W,[M,N,3, v_final, m_final];
    W=permute(W,[4,5,3,1,2]);

In this form, one can lookup complete arrays of size v_final x m_final or of size v_final x m_final x 3 by doing things like;

w1=W(:,:,1,x,y);
w2=W(:,:,2,x,y);
w3=W(:,:,3,x,y);
wij=W(:,:,1:3,x,y);

Thanks Matt...I appreciate!
