title: Add more sample points to data
body: <p>Given some data of shape 20x45, where each row is a separate data set, say 20 different sine curves with 45 data points each, how would I go about getting the same data, but with shape 20x100?</p>
  
  <p>In other words, I have some data A of shape 20x45, and some data B of length 20x100, and I would like to have A be of shape 20x100 so I can compare them better.</p>
  
  <p>This is for Python and Numpy/Scipy.</p>
  
  <p>I assume it can be done with splines, so I am looking for a simple example, maybe just 2x10 to 2x20 or something, where each row is just a line, to demonstrate the solution.</p>
  
  <p>Thanks!</p>
