MATLAB: How to ignore some elements of function returned vector

return valuevector elements

When writing my code, I need some elements from the returned vector. For example:
 y=zeros(100,1003);
for ii=1:100
 y(ii,:)=conv(h(ii,:),x(ii,:));
end
I just want y(:,4:end); and I my solution is:
 y(:,1:3)=[];
I think that matlab should have an elegant expression for this case. Is there any suggestion. Something like:
 y=zeros(100,1000);
for ii=1:100
y(ii,:)=conv(h(ii,:),x(ii,:))(4:1003); %of course it's not correct :(
end
Thanks in advance 🙂

I am sure that knowing what is h and x would give some other ideas, but, Why don't you just do this?:
y = zeros(100,1000);
for ii=1:100
  tmp = conv(h(ii,:),x(ii,:));
  y(ii,:) = tmp(4:end);
end
