I think your problem is this:
You call a function, whose result is a vector, from which you need only specific values. In Matlab, you can't combine those two things. (If you use cells, you can most of the times)
for i=1:NumFrames
temp=fft(windowed(i,:));
ft(i,:)=abs(temp(1:frameSize/2));
%you need to be sure that frameSize is even, if you are not, use round(frameSize/2)
end
