matlab fixed point iteration jumping down to zero after stabilizing at fixed point

When I apply the simple loop;
for i =1:50
B(i+1)=1/2*(B(i)+(9/B(i)))
end
My list gives me the right answer $3$ but then after a a few iterates it jumps down to zero. Does anyone know what that is about?

I cannot reproduce this with initial values ofBequal to 1, 2, and 10. Please provide a Minimal, Complete, and Verifiable example that produces the output you're seeing.

The only way I can imagine is that the array B is longer than 51 elements and elements after index 51 were initially set to zero.
