Well, I've tried it now and looks I got it right, check the code below... can you confirm if I nailed it please?

THANKS Cheers

Theory is in: http://msp.ucsd.edu/techniques/latest/book-html/node140.html and an example (actually a shelving filter but give the "rzero" a coefficient of zero to get a pure low-pass) : H11.shelving.pd
