public class Function_0
extends Function

This class Function_0 represents a generic Type 0, sampled function type. Type 0 functions use a sequence of sampled values (contained in a stream) to produce an approximation for function shose domains and ranges are bounded. The samples are organized as an m-dimensional table in which each entry has n components.

Sampled functiosn are highly general and offer reasonablly accurate representations of arbitrary analytic functions at low expense. The dimensionality of a sampled function is restricted only by the implementation limits.

Since:
