Class CSplineInterpolator

java.lang.Object
  org.jcurl.math.R1RNFunctionImpl
      org.jcurl.math.R1R1Function
          org.jcurl.math.CSplineInterpolator

All Implemented Interfaces:

Serializable, R1RNFunction

public class CSplineInterpolator
extends R1R1Function

The numerical algorithms are adapted from "Meyberg/Vachenauer": Hoehere Mathematik I, second edition. Could this be based on CurveCombinedwith 3-dimensional polynomes?

Constructor Detail

CSplineInterpolator

public CSplineInterpolator()

Create a new spline interpolator with an initial capacity of 100 points.

CSplineInterpolator(int)

CSplineInterpolator

public CSplineInterpolator(int capacity)

Create a new spline interpolator with the given initial capacity.

Parameters:

capacity -

Method Detail

add

public void add(double x,
                double y)

Add a point and discard the splines. The x-values must be strictly monotonous ascending - which is not checked for the moment. Reallocates the point buffer if necessary.

Parameters:

x -

y -

at

public double at(double x,
                 int C)

Convenience wrapper.

Specified by:

at in class R1R1Function

Parameters:

x - location

C - n'th derivative (0=value,1=incline,2=acceleration)

Returns:

value ot the n'th derivative

getMaxX

public double getMaxX()

getMinX

public double getMinX()

reset

public void reset()

Discard the buffered points and splines.
