Searching the location of a specific cell in a cell array

Hello community! I have a cell array (1x1000) like this {[1 2], [3 5], [4,2],..., [2 5]} I found the most commonly occurring cell in this, but now I want to find the positions of this cell. Example what is the position of cell [2 5]? and the answer I want to be the (1, 100) (1,205) (1,276) etc

Please help, if anyone knows.

v={[1 2], [3 5], [4,2],[3 5] ,[4 2]} 
w=cell2mat(v')
idx=find(ismember(w,[4,2],'rows'))

its working but no 100% , something is missing. I forgot to refer that there are some empty cells, does it causes a problem?
