title: Difference between Numpy and Numpy-MKL?
body: <p>I wanted to test some signal processing and statistics using SciPy.
  So I had to use <code>scipy.signal</code> and <code>scipy.stats</code>, but I always used to get an error:</p>
  
  <p><code>ImportError: DLL load failed: The specified module could not be found.</code></p>
  
  <p>I was using Numpy 1.7.1, scipy 0.12 and Python 2.7.3. I checked on the internet and asked about it on other forums too!
  This problem got solved when switched my Numpy distribution with the Numpy-MKL distribution.</p>
  
  <p>I want to know the difference between the two libraries ?</p>
