Add more sample points to data
If your application is not sensitive to precision or you just want a quick overview, you could just fill the unknown data points with averages from neighbouring known data points (in other words, do naive linear interpolation).
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?
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.
This is for Python and Numpy/Scipy.
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.
Thanks!
