title: Import numpy files from a downloaded zip to use in python script
body: <p>I have downloaded the numpy zip file, and have unzipped it in the folder where my project is located. I used the code</p>
  
  <pre><code>from numpy import *
  </code></pre>
  
  <p>but when I try to use the functions, such as the matrix function, from numpy the matrix class apparently doesn't exist. I am very new to python, so maybe an explanation about how to include files in python is also due. </p>
