How can I fix this?

Right now I am trying to recreate an equation using MATLAB, but I am seeing some discrepancies between the solution I got from the calculator and the MATLAB.

This is the equation I am trying to recreate in MATLAB: with n being a matrix. The code I've written for this equation in MATLAB looks like this:

y = 1/1+exp(-n)

So for example if I am trying to find y with n = , my expected answer should be = [0.99; 0.12; 0.00012] but in MATLAB I am getting:

y = 
   1.0e+03 *

    0.0010
    0.0084
    8.1041

which is obviously not what I want. I am certain it's a simple mistake, but I can't figure it out. What am I doing wrong? How can I fix this?

 y = 1./(1+exp(-n))

Thank you very much! I tried ./ and () each by themselves before but it never occured to me to do them together at the same time. Really, thank you very much!!
