I am trying to set up an array of values with lower and upper bounds. The lower bound (lb) is .1 and the upper bound (ub) is .25. I also have a table called Tab. I want to find all values in Tab(:,3) as long as they are within [lb and ub]. I am trying to use ismember because I am specifying for other columns using ismember. It would be nice if I could extract all rows from Tab(:,3) that fall between ub and lb using ismember. Any help?
