title: Python: NxM array of samples drawn from NxM normal distributions
body: <p>I have two 2D arrays (or of higher dimension), one that defines averages (M) and one that defines standard deviations (S). Is there a python library (numpy, scipy, ...?) that allows me to generate an array (X) containing samples drawn from the corresponding distributions?</p>
  
  <p>In other words: each entry x<sub>ij</sub> is a sample that comes from the normal distribution defined by the corresponding mean m<sub>ij</sub> and standard deviation s<sub>ij</sub>.</p>
