For a<br>> weighted sum, "the total number of values" is the sum of the weights,<br>> which in this case is zero.<br>> <br>> I'd suggest that r.mfilter may be more appropriate for implementing<br>> discrete convolution (FIR) filters.<br>> <br>> -- <br>> Glynn Clements <glynn@gclements.plus.com><br></div> </div></body>
