1. The first thing you need to know is that in Matlab, the array index starts from 1 and not from 0. So if you write x(0)=1, you would get an error.
So you need to modify your limits to x[n]= 1 ; 1<=n<=10 and N<=10.
2. The statement
N<=9;
will give you a true or false answer as it is a logical statement. Also, the answer would be of no use as it is not being stored or used as a flag in any way.
3. As for the boundary, you can simply add a if statement inside a for loop.
for ii=1:length(h)
if ii>=1 && ii<=N % considering you have added 1 as described in 1
h(ii)=1;
else
h(ii)=0;
end
end
