title: calculating rowwise minimum of two series?
body: <p>Hi;</p>
  <p>Is there any function that can generate a serie by calculating rowwise minimum of two series.? Functionality will be similar to np.minimum</p>
  <p>a = [1,4,2,5,2]
  b= [5,1,4,2,5]</p>
  <p>np.minimum(a,b) -&gt; [1,1,2,2,2]</p>
  <p>Thanks.</p>
