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.

Warning:

See the Interpolation class for information about the required lifetime of the underlying data.
