Q1:
[H] = make_bank_DFT(wincoeff,nbands);
This matlab code returns DFT filter bands, H.
So, there are 'nbands' filters in H.
How can I take out each subband filter to deal with it separately?
For example I need to take out only the third subband filter, how can I do that?

Q2:
xD = upfirdn(s,H,1,D);
The same question is for the above decimator; How can I take out, for example, the third decimator?

Thanks
