Search non-string elements in a cell array

I built a cell array that contains non-string elements, say, vectors containing numbers.

How can I search if a vector exits in this cell array? Since the elements are not strings, I cannot use ismember() function.

Concretely, if I had a cell array like 

a = {[1 2], [2 3], [3 4], [4 5]}

how can I find out if [2 3] is in this cell array?

You can try this :

ismember(num2str([2 3]), cellfun(@num2str, a, 'UniformOutput', false))

I think this should work: 

find(ismember(cell2mat(a'),[2 3],'rows'));

or if you don't need the location:

any(ismember(cell2mat(a'),[2 3],'rows'));

Good luck =)
