end
end
for i=1:a-1
d=(poortext1(:,:,i));
subplot(4,4,i)
imshow(d);
title('poor-texture');
end
figure
for i=1:b-1
d1(:,:,i)=(text1(:,:,i));
d2=d1(:,:,i);
subplot(4,4,i)
imshow(d2);
title('texture');
end
could anyone help me to solve the error. thanks in advance.

mat2cell has to be told how to split every dimension. You are splitting rgb images and those are 3 dimensional so you have to tell mat2cell how to process the third dimension. If you do not want to split along the third dimension then add an additional argument which is the size of the third dimension.
