How can I a void this nested loop?

How could I vectorize this nested loop?

M1=[4 5 6; 9 8 7];

P= [2 3 4; 1 2 3];

for k=1 : 2

      for j=1 : 3

          pn(k,j)= normrnd(M1(k,j), (max(P(:,j)) - min(P(:,j))) ); 

      end 

end

I need to use the normrnd function for each element in the M1 matrix that's why I do it by this way. If I could avoid this loop I can save the time. Any help will be appreciated.

Thanks in advance.

    pn = normrnd(M1,repmat(max(P,[],1)-min(P,[],1),2,1));

I'm inclined to doubt that this will save you any significant amount of execution time, however.
