When I try
b = fir1(nfilt,0.01,'low','hamming','scale');
I get an fir2 error "window must be of length n+1"
Anybody got an idea? Thanks.

Try: b = fir1(nfilt,0.01,'low', hamming(nfilt+1),'scale') instead.
(nfilt is the number of delays, not coeffs)
Don't know why passing just the window name doesn't work.
