Hard to understand what you are asking. A simple example would be beneficial.

Simplified example:

array=randi(10,5)

array = 5×5

10 10 7 2 4 4 7 10 7 10 1 8 4 2 7 3 7 10 5 5 9 7 10 10 2

test=array(:,5)>4; 

subset=array(test,:) %rows where 5th column is greater than 4

subset = 3×5

4 7 10 7 10 1 8 4 2 7 3 7 10 5 5
