Remove outliers from signal

Hello! I have a signal and I need to remove outliers from it.

if Atlas(i)-10>= Atlas(i+1);
     nreal(i )=0;
     else Atlas((i)+10<= Atlas((i+1);
     real(i)=Atlas(i);  
end

Error Index exceeds matrix dimensions.

I do not understand how to correct this error.

Atlas = 1x12003

i=12003

Show us the full code......with the dimensions if each variable.

Atlas=trapz(MarchData) ;
ave=rand(1,12003);
for i= 1:length(ave)-1
if Atlas(i)-10>= Atlas(i+1);
     nreal(i )=0;
     else Atlas((i)+10<= Atlas((i+1);
     real(i)=Atlas(i);  
end
