title: How can I create a numpy array holding values of a multi-variable function?
body: <p>I want to create an array holding a function <code>f(x,y,z)</code>.  If it were a function of one variable I'd do, for instance:</p>
  
  <pre><code>sinx = numpy.sin(numpy.linspace(-5,5,100))
  </code></pre>
  
  <p>to get <code>sin(x)</code> for <code>x</code> in <code>[-5,5]</code></p>
  
  <p>How can I do the same to get, for instance <code>sin(x+y+z)</code>?</p>
