title: Interpolation of gridded data
body: <p>I was hoping someone could help me with a problem that Ive been having (I'm still very new to python). I have been trying to interpolate data from a 50x4 array that is read from an excel sheet seen below.</p>
  
  <pre><code> [ 60.      0.     23.88   22.38 ]  
   [ 60.      5.     19.508  28.2  ]  
   [ 60.     10.     16.9    32.23 ]  
   [ 60.     15.     15.4    34.03 ]  
   [ 60.     20.     14.4    35.12 ]  
   [ 60.     25.     13.66   36.02 ]  
   [ 60.     30.     13.14   36.61 ]  
   [ 60.     35.     12.69   37.14 ]  
   [ 60.     40.     12.53   37.56 ]  
   [ 60.     50.     12.33   38.32 ]  
   [ 70.      0.     19.3    21.34 ]  
   [ 70.      5.     16.06   25.37 ]  
   [ 70.     10.     13.74   28.08 ]  
   [ 70.     15.     12.33   40.07 ]  
   [ 70.     20.     11.45   41.78 ]  
   [ 70.     25.     10.77   42.8  ]
  </code></pre>
  
  <p>etc...</p>
  
  <p>What I'm trying to achieve is to enter 2 values (say 65 and 12) which correspond to interpolated values in the 1st and 2nd column, and it would return the interpolated values for columns 3 and 4. I managed to get it working using the griddata function in matlab. However no luck in python yet.</p>
  
  <p>Thanks in advance</p>
