I have a cell array P= {[2,5], [3], [], [1,14], [], [9]}. I want to find out the number of cell where value 14 is located. Like, here 14 is located inside the cell number 4.
How can I do that?

P= {[2,5], [3], [], [1,14], [], [9]} ;
N = length(P) ;
val = 14 ;
for i = 1:N
idx = ismember(14,P{i}) ;
if any(idx)
break
end
end
i
P{i}
