Subscript indices must either be real positive integers or logicals.

Error in ==> svlzfsig2>remTrend at 54 rm=rm(winSize/2:length(rm)-winSize/2);

Error in ==> svlzfsig2>zeroFreqFilter at 41 zfSig=remTrend(zfSig,winLength);

Error in ==> svlzfsig2 at 17 zf=zeroFreqFilter(wav,fs,winLength);

Error in ==> EpochsbyZFF at 40 [zsp1,gclocssp1,epssp1,f0sp1]=svlzfsig2(sp1sig,fs,winlength);

Error in ==> UVRegion at 10 [zsp1,epochlocs,vgclocssp1,vf0sp1,vepochstr]=EpochsbyZFF(s,Fs);

Error in ==> hari_new at 36 [epochlocs,vgclocssp1_3,UvRegion,vf0sp1_3,vepochstr]=UVRegion(part3,Fs);

You have to tell us what the sizes are of the variables in

rm=rm(winSize/2:length(rm)-winSize/2);

put a breakpoint in the code at that line and see what the dimensions are of rm and winSize

winSize is probably an odd number, like 5, so winSize/2 would be a fractional number like 2.5. There is no 2.5th element of the array. There is element #2 and element #3. You have to decide to use only even window sizes, or decide what to do in the case of an odd sized window.

function [zfSig]=zeroFreqFilter(wav,fs,winLength) dwav=diff(wav); dwav(end+1)=dwav(end); dwav=dwav/max(abs(dwav)); N=length(dwav); zfSig=cumsum(cumsum(cumsum(cumsum(dwav)))); winLength=round(winLength*fs/1000); zfSig=remTrend(zfSig,winLength); zfSig=remTrend(zfSig,winLength); zfSig=remTrend(zfSig,winLength); zfSig(N-winLength*2:N)=0; zfSig(1:winLength*2)=0; function [out]=remTrend(sig,winSize)

window=ones(winSize,1); 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 is the code can u tell me where should i change such that it only allows evn numbers
