Because it's an infinite loop. You set z outside the loop and do not change it inside the loop, so z is always between 0 and 5 and eventually v will get so large that Matlab crashes. Try using v(3) instead of z. Also, what is the point of this: rand(1000); It's telling Matlab to create a 1000x1000 matrix of data, but you're not assigning it to anything.
