how to get 3 indices of the min value?

hey guys,I built this function:

err=zeros(15,15,15);
for p=-7:7;
    for r=-7:7;
        for q=-7:7;
            zR=gwl*p*1.12+xR;
            zG=gwl*q+xG;
            zB=gwl*r*0.88+xB;
            h=0.33*(abs(zR-zB)+abs(zB-zG)+abs(zR-zG));
            err(8+p,8+r,8+q)=h;
         end
    end
end

and now i need know the 3 indices of the min value of err, any ideas how to achieve it?

thanks in advance

   [~,ix] = min(err(:));
   [i1,i2,i3] = ind2sub(size(err),ix);

The minimum value is err(i1,i2,i3).

thanks that does the work!
