I discovered the answer to my own question, it was decided to store the two boundry points from the array and the use cellfun to implement the logic. Here is my code for future viewers if they have a similar question.
% code
Latmax = num(1,1);
Latmin = num(2,1);
OutOfRangeLat = cellfun(@(x) (x > Latmin) & (x < Latmax), LatitudeColumn, 'Uni',0);
NrOutOfRangeLat = sum('OutOfRangeLat');
