Why won't this equality work?

I got my top 17 values and I need to obtain a set corresponding values with it. I tried to use a code I used beforehand but it was comparing a single value, not a matrix where I think my problem resides. When ran it goes through obtainining none of the secondary values (Ts).

wh17=maxk(w(:,3),17);

Hs=mean(wh17);

for i=1:50

if w(i,3)==wh17(:)

Ts=w(i,2)

end

end

wh17=maxk(w(:,3),17);
Hs=mean(wh17);
Ts=w(ismember(w(:,3),wh17),2);
