Class RealFunctionOnIndex

java.lang.Object

de.jtem.function.real.RealFunctionOnIndex

All Implemented Interfaces:

Domain.OnIndex, RealFunction.OnIndex

public class RealFunctionOnIndex
extends Object
implements RealFunction.OnIndex

An implementation of the interface RealFunction.OnIndex. Function values are stored internally, so using this class to make a copy of a RealFunction.OnIndex c (by the corresponding constructor or the assign method) will make a snapshot of the current state of c. No reference to c itself is retained.

Constructor Summary

Constructors

Constructor and Description
RealFunctionOnIndex()
RealFunctionOnIndex(double[] c) Interpret the array c as an n-tupel of and create a copy of it.
RealFunctionOnIndex(int n) Creates a tupel of n zeroes.
RealFunctionOnIndex(RealFunction.OnIndex c) Creates a copy of the tupel c

Method Summary

Modifier and Type	Method and Description
void	assign(double[] c) Interpret the array c as an n-tupel and become a copy of it.
void	assign(RealFunction.OnIndex c) Become a copy of the tupel c
void	assignZero() Keep the number of indices but set all values to zero.
void	assignZero(int n) Become a tupel of n zeroes.
int	getNumIndices() Returns the number of indices (a non-negative integer).
protected void	setNumIndices(int n) Do nothing if n is equal to the current number of indices, become a tupel of n zeroes otherwise.
void	setValueAt(int j, double x) Set the value at index j to x.
double	valueAt(int j) returns the value of this function at j.
