can anybody help me with tthis function ???

function [out]=remTrend(sig,winSize)

window=ones(winSize,1); %window(winSize/2-3:winSize/2+3)=0; rm=conv(sig,window); rm=rm(winSize/2:length(rm)-winSize/2);

norm=conv(ones(size(sig)),window); norm=norm(winSize/2:length(norm)-winSize/2);

rm=rm./norm; out=sig-rm; return; this code constructs the value that gets written into winSize ,i need 2 change the function such that it only allows even numbers or winSize to be evn

What do you want it to do if the winSize passed in is odd or zero ?
