Constructor Detail

MicrosphereInterpolator

public MicrosphereInterpolator()

Deprecated.

Create a microsphere interpolator with default settings. Calling this constructor is equivalent to call MicrosphereInterpolator(MicrosphereInterpolator.DEFAULT_MICROSPHERE_ELEMENTS, MicrosphereInterpolator.DEFAULT_BRIGHTNESS_EXPONENT).

MicrosphereInterpolator

public MicrosphereInterpolator(int elements,
                               int exponent)
                        throws NotPositiveException,
                               NotStrictlyPositiveException

Deprecated.

Create a microsphere interpolator.

Parameters:

elements - Number of surface elements of the microsphere.

exponent - Exponent used in the power law that computes the weights (distance dimming factor) of the sample data.

Throws:

NotPositiveException - if exponent < 0.

NotStrictlyPositiveException - if elements <= 0.

Method Detail

interpolate

public MultivariateFunction interpolate(double[][] xval,
                                        double[] yval)
                                 throws DimensionMismatchException,
                                        NoDataException,
                                        NullArgumentException

Deprecated.

Computes an interpolating function for the data set.

Specified by:

interpolate in interface MultivariateInterpolator

Parameters:

xval - the arguments for the interpolation points. xval[i][0] is the first component of interpolation point i, xval[i][1] is the second component, and so on until xval[i][d-1], the last component of that interpolation point (where d is thus the dimension of the space).

yval - the values for the interpolation points

Returns:

a function which interpolates the data set

Throws:

DimensionMismatchException - when the array dimensions are not consistent.

NoDataException - if an array has zero-length.

NullArgumentException - if the arguments are null.
