title: MATLAB, Phased Array Toolbox and `pattern` function
body: <p>I'm trying to understand an <a href="http://www.mathworks.com/help/phased/examples/subarrays-in-phased-array-antennas.html" rel="nofollow">example</a> for MATLAB Phased Array Toolbox.</p>
  
  <p>There is called function <code>pattern</code>:</p>
  
  <pre><code>pattern(ha,fc,-180:180,0,'Type','powerdb',...
      'CoordinateSystem','rectangular','PropagationSpeed',c)
  </code></pre>
  
  <p>Cannot you tell me, where is the function described and what does it do?</p>
