Detailed Description

base class for 2-D interpolations.

Classes derived from this class will provide interpolated values from two sequences of length $ N $ and $ M $, representing the discretized values of the $ x $ and $ y $ variables, and a $ N \times M $ matrix representing the tabulated function values.
