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);
