This is my original code without parfor
For i1=1:1:nrr1
disp(i1);
if (varran(i1) < threshold)
labe(i1)=0;
mvqcoder(e)=[meanranr(i1)];
mvqcodeg(e)=[meanrang(i1)];
mvqcodeb(e)=[meanranb(i1)];
e=e+1;
mvqcode=cat(3, mvqcoder, mvqcodeg, mvqcodeb);
else
labe(i1)=1;
[domr]=domsearch(rang1r(i1,:),dompoolr,gsize,ci1r(i1),ci2r(i1),ci3r(i1),msr(i1),mdr,cd1r,cd2r,cd3r,mscr);
[domg]=domsearch(rang1g(i1,:),dompoolg,gsize,ci1g(i1),ci2g(i1),ci3g(i1),msg(i1),mdg,cd1g,cd2g,cd3g,mscg);
[domb]=domsearch(rang1b(i1,:),dompoolb,gsize,ci1b(i1),ci2b(i1),ci3b(i1),msb(i1),mdb,cd1b,cd2b,cd3b,mscb);
dom=[domr,domg,domb];
[rz cz]=size(dom);
meanrar=mean(rang1r(i1,:));
meanrag=mean(rang1g(i1,:));
meanrab=mean(rang1b(i1,:));
meanra=cat(3,meanrar ,meanrag,meanrab);
for z=1:1:cz
dompolr(z,:)=dompoolr(dom(z),:);
end
for z=1:1:cz
dompolg(z,:)=dompoolg(dom(z),:);
end
for z=1:1:cz
dompolb(z,:)=dompoolb(dom(z),:);
end
dompol=cat(3,dompolr,dompolg,dompolb);
[isomer alphr meanrr dom1r errr]=affwerrqt(rang1r(i1,:),dompolr(1:cz,:),gsize);
[isomeg alphg meanrg dom1g errg]=affwerrqt(rang1g(i1,:),dompolg(1:cz,:),gsize);
[isomeb alphb meanrb dom1b errb]=affwerrqt(rang1b(i1,:),dompolb(1:cz,:),gsize);
cdom1r(w1)=dom(dom1r);
isome1r(w1)=isomer;
alph1r(w1)=alphr;
meanr1r(w1)=meanrar;
cdom1g(w1)=dom(dom1g);
isome1g(w1)=isomeg;
alph1g(w1)=alphg;
meanr1g(w1)=meanrag;
cdom1b(w1)=dom(dom1b);
isome1b(w1)=isomeb;
alph1b(w1)=alphb;
meanr1b(w1)=meanrab;
cdom1=cat(3,cdom1r,cdom1g,cdom1b);
isome1=cat(3,isome1r,isome1g,isome1b);
alph1=cat(3,alph1r,alph1g,alph1b);
meanr1=cat(3,meanr1r,meanr1g);
vqcode3r(c,:)=[isome1r(w1),alph1r(w1),meanr1r(w1),cdom1r(w1)];
vqcode3g(c,:)=[isome1g(w1),alph1g(w1),meanr1g(w1),cdom1g(w1)];
vqcode3b(c,:)=[isome1b(w1),alph1b(w1),meanr1b(w1),cdom1b(w1)];
c=c+1;
vqcode3=cat(3,vqcode3r,vqcode3g,vqcode3b);
end
w1=w1+1;
end
Any one please give me a solution for this problem .

The part of that code that can be translated to use "parfor" would come out as,
parfor i1=1:1:nrr1
if (varran(i1) < threshold)
labe(i1)=0;
else
labe(i1)=1;
end
end
The rest of the code in your "for" loop depends upon the order of executing the iterations and so cannot be changed to use "parfor".
