1)
for ii=1:length(yy1)%yy1 contains 2 cells of size 192x192x3
dwt{1,ii}=dwt(yy1{ii},'db4');% i need to store approximation coefficient alone.
end
2)
for ii=1:length(yy1)
dct{1,ii}=dct2(yy1{ii});% error is 'matrix dimension must agree'
end

dwt is for vectors. dct2 is for 2 dimensional arrays. You are trying to pass in 3 dimensional arrays.

It looks to me as if you might have a corrupted installation or else a corrupted path. Try
resetdefaultpath
and then try again. If that fails you need to reinstall the wavelet toolbox.
