How to find the position of a number in an cell-array?

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?

how do i create my own question ?

Hi yaish, you need to go 'ask' in the top.

Answer 1

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}

its not working. I got P{i}= 1 14. But it should be cell number 4

[KSSV]

i is the cell number friend. P{i} gives you the values in the cell.

Thank you. I got it.

I also find a another way, just sharing here.

 out = cellfun(@(x) find(x == 14),P,'un',0);
 idx = cellfun('isempty',out);
 i=find(~idx)

cellfun uses loop behind. find will be slow.
