k1=1;
for i=19:29
imag4=imscram(:,:,i);
subplot(:,:,i);
imshow(imag4);
[lllo,lhlo,hllo,hhlo]=dwt2(double(imag4),'haar');
llw(:,:,k1)=lllo(:,:);
lhw(:,:,k1)=lhlo(:,:);
hlw(:,:,k1)=hllo(:,:);
hhw(:,:,k1)=hhlo(:,:);
k1=k1+1;
figure
end

If subplot() is an array, then
subplot(:,:,i);
is at best a waste of time, as that would extract a portion of the array and then throw the extracted value away because of the semi-colon. If the array had a third dimension smaller than 29, you would get an error about the index exceeding the dimension.
If subplot() is the MATLAB plotting function, then passing a colon to it is not valid.
