title: Location of minimum in Julia
body: <p>Does Julia have a build in command to find the index of the minimum of a vector?  R, for example, has a <code>which.min</code> command (and a <code>which.max</code>, of course).  </p>
  
  <p>Obviously, I could write the following myself, but it would be nice not to have to.</p>
  
  <pre><code>function whichmin( x::Vector )
    i = 1
    min_x=minimum(x)
    while( x[i] &gt; min_x ) 
      i+=1 
    end
    return i
  end
  </code></pre>
  
  <p>Apologies if this has been asked before, but I couldn't find it.  Thanks!</p>
