Setting conditions for optimization variables

We are now setting the conditions for the following optimization variables.

x = optimvar('x', 100, 'LowerBound', 0)

showbounds(x)

Then,

0<=x(1)

0<=x(2)

・・・

0<=x(100).

How do we write the code to add the following condition?

We want to add an upperbond=0 in the interval 1 < x < 10.

0<=x(1)<=0

0<=x(2)<=0

・・・

0<=x(10)<=0

0<=x(11)

0<=x(12)

・・・

0<=x(100)

Thank you for your nice answer!!

x = optimvar('x', 100, 'LowerBound', 0);
ub = Inf(100,1);
ub(1:10) = zeros(10,1);
x.UpperBound = ub;
showbounds(x)

It would probably be better to remove x(1) through x(10) from your problem, but suit yourself.
