openpathsampling.numerics.LookupFunction

class openpathsampling.numerics.LookupFunction(ordinate, abscissa)[source]

Interpolation between datapoints.

Parameters
  • ordinate (iterable of numbers) – values for the ordinate

  • abscissa (iterable of numbers) – values for the abscissa

  • number. (Iteration and numpy ufuncs work on the values. Callable with any) –

Notes

Largely, this class mimics an immutable dictionary, except instead of implementing __getitem__, we use the __call__ function. If you call a number that is in the dictionary, you get exactly that number. If you call a number that it not in the dictionary, the get the linear interpolation/extrapolation for that number based on the dictionary values.
