I want to remove the NaN column and row in my image so the size will be decreased, but since I used the "find' command it Matlab, it also remove the NaN that changes the shape of the image,too. I just want to remove the NaN data as much as possible but keep the other NaNs that cannot be removed in order to have the same shape.
