title: Scipy fmin argument passing
body: <p>so I'm just a bit confused as to how scipy.optimize.fmin takes arguments</p>
  
  <p>say I have two functions:</p>
  
  <pre><code>def func_1(x, y):
     return (x*x) + (y*y)
  
  def func_2(x, y, a):
     return ((x-a)*(x-a)) + ((y-a) *(y-a))
  </code></pre>
  
  <p>in func_1 I simply want the min values for x and y, and in func_2 I'd ideally like to pass a value for a , and then find the min vals for x and y. I've read some of the other questions in regard to this, and am still a bit confused. </p>
  
  <p>Attempts to call : <code>fmin(fund_1, [1,1])</code> results in :  <code>fmin() takes at least 2 arguments (1 given)</code></p>
  
  <p>Many thanks!</p>
