public class Spline

extends BaseSpline

The class supports a 1D or multi-D spline value calculation in any point of the space of independent variables. For the 1D spline, the calculation of a spline derivative is also possible if the spline body permits this operation.

Constructor Detail

Spline

public Spline(SplineBody body)

Constructor (creates spline coefficients container).

Parameters:

body - a spline body

Spline

public Spline(SplineBody body,
              RealContainer data)

Constructor.

Parameters:

body - a spline body

data - a spline coefficients container

Method Detail

getVector

public final RealVector getVector()

Returns the vector of spline coefficients.

value

public final double value(double point)

Calculates a spline value at a point required. May be used for 1D splines only. A point is a point on the real axis.

Parameters:

point - a point on the real axis

Returns:

the spline value

value

public double value(double point,
                    int index)

Calculates a spline derivative at a point required. May be used for 1D splines only. A point is a point on the real axis and an index is a derivative index to be calculated. index=0 means a spline value calculation.

Parameters:

point - a point on the real axis

index - a derivative index

Returns:

the spline derivative value

value

public double value(RealPointer point)

Calculates a spline value at a point required. May be used for any (1D or multi-D) spline. A point vector means a point in the space of independent variables.

Parameters:

point - a point in the space of independent variables

Returns:

the spline value
