finding the exact location of empty cells

Dear all,
I have the following cell matrix
clear all
clc
k = cell(2,6)'
k{1} = '7';
k{12} = 3;
To find empty cells I use the usual command
pp=cellfun(@isempty,k)
But I can not "see" the exact position of the empty cells.
For example one empty cell is at the position (1,2)
I tried I=find(pp); and I got as a result the following
2
3
4
5
6
7
8
9
10
11
where I suppose 2 corresponds to (1,2). But this is not very explicit about which positions of the matrix are empty. And in my case I have matrices of huge dimensions
Any help is greatly appreciated

Use two output arguments for the find() command:
[i,j] = find(pp);
