cell & ismember or intersect

r=cell(10);
r{1,1}=1:5;
r{1,5}=6:10;

In the example abvoe, I would like to know the location of
6, which is the 5th array of cell. I used intersect or
ismember to find the location, but it didn't work. It says
that it should be "string" in order to use "intersect" or
"ismember" in cell array. I am trying to avoid loop and
"string" to perform such functions in huge simulations.

In the same example above, I also would like to find the
first empty cell. Would you help me to do it? I used a loop
"for", but in my huge simulations, I would like to avoid
this loop.

Thanks in advance.

Hi,
CELLFUN may help :
[i,j]=find(cellfun(@(x)ismember(6,x),r))
