Multidimensional array search cell

Hi I have a function where I need to search a multidimensional array to see if it matches a 1x2 matrix.

For example I have pcandidate = [1,1] CLOSED{j} where j is the number of 2x1 matrixes in the feature.

I want to search to make sure from 1:j that none contain the candidate. The list gets up to 2000 so i was trying to achieve something more efficient then looping

It's not very clear what the structure and type of your data is (You talk about matrices but then use the {} notation which is for cell array and the dimension of your data jumps from 1x2 to 2x1). In any case, the function you want is ismember:

pcandidate = [1 1];
closed = [1 5
          1 1
          3 4];
ismember(pcandidate, closed, 'rows') %return true

closed = [1 5
          2 2
          3 4];
ismember(pcandidate, closed, 'rows') %return false
