For example, if I had:
x = zeros(1,100)
and I wanted to make the 3rd, 5th, 67th, and 93rd element equal to one, how could I do this?

x([3, 5, 67, 93]) = 1;

But the problem in this solution the newly generated vector will be with 93 elements, so how to keep the new-x as 100 elements after the solution?

No, with that code, the size of x will not change unless it had fewer than 93 elements. But the user said that x = zeros(1,100) so we know that it already exists with 100 elements.
