MATLAB: If any a can be index

Question

           A(n)=1;

Answer 1

Perhaps this:

VV=8;
v=length(y);
n=0;
for  k=1:VV:length(y)
       n = n + 1;
       if any(y(k:k+8))
           A(n)=1;
       else
           A(n)=0;
       end
end

By the way, are you sure you don't want k:(k+7) instead of k:k+8?
