I don't really understand what you're attempting to do with the while loop, but yes, there is a faster way. It requires you to think a bit more.
log2(realmax)
OK, so we are looking for x where e^x is at most 2^1024.
With a little bit of algebra that should not be too hard to solve. Can you see how?

All data creates in MATLAB are douple precision (Standard /By Default)
More:
e^x = 1 + (x ^ 1 / 1!) + (x ^ 2 / 2!) ......
