It sounds like you are only interested in assessing row 1 and column 1 which are vectors of two different lengths. If you want to do something different, please explain more clearly the goal.

abc_data = rand((randi(20)),2)
abc_data = 12×2
    0.8582    0.4476
    0.4260    0.6028
    0.7803    0.1592
    0.2553    0.5614
    0.5697    0.3633
    0.9326    0.7562
    0.9734    0.7677
    0.4696    0.7044
    0.7278    0.8881
    0.1457    0.4547
% For row 1
abc_data(1,:) > 0.5
ans = 1×2 logical array
   1   0
% For col 1
abc_data(:,1) > 0.6
ans = 12×1 logical array
