Get original indices of a sorted numpy array
<p>Hi I have an array of distances <code>a= np.array([20.5 ,5.3 ,60.7 ,3.0 ], 'double')</code> and I need the indices of the sorted array (for example <code>[3, 1, 0, 2]</code>, for <code>a.sort()</code>). There is a function in numpy to do that?</p>

<p>Thanks</p>
