How can I use a for loop to select values from a table that meet two conditions?

My table is tab=table(metabolites, aerobic, anaerobic).

I am trying to compute a for loop that only selects those metabolites where they are >=0 in each aerobic and anaerobic columns and where they also different value in each column for each row.

I am not too sure how I can change the below for loop to say the above, as it is currently wrong. I would be grateful for any suggestions please. Thank-you

m=1
for i=1:height(tab)
    if(Aerobic(i)~=Anaerobic(i)) &
        (Aerobic(i) & Anaerobic(i) >=0)
        secmet(m, 1:3)=tab(i, 1:3)
        m=m+1
    else
        continue;
    end
end

m=1;
for i=1:height(tab)
    if(Aerobic(i)~=Anaerobic(i)) &&  Aerobic(i)>=0 && Anaerobic(i)>=0
        secmet(m, 1:3)=tab(i, 1:3)
        m=m+1
    else
        continue;
    end
end

Just need to change the logical expresssion
