Constructor Details

BicubicSplineInterpolator

public BicubicSplineInterpolator()

Deprecated.

Default constructor. The argument initializeDerivatives is set to false.

BicubicSplineInterpolator

public BicubicSplineInterpolator(boolean initializeDerivatives)

Deprecated.

Creates an interpolator.

Parameters:

initializeDerivatives - Whether to initialize the internal data needed for calling any of the methods that compute the partial derivatives of the function returned from the call to interpolate.

Method Details

interpolate

public BicubicSplineInterpolatingFunction interpolate(double[] xval,
 double[] yval,
 double[][] fval)
                                               throws NoDataException,
DimensionMismatchException,
NonMonotonicSequenceException,
NumberIsTooSmallException

Deprecated.

Compute an interpolating function for the dataset.

Specified by:

interpolate in interface BivariateGridInterpolator

Parameters:

xval - All the x-coordinates of the interpolation points, sorted in increasing order.

yval - All the y-coordinates of the interpolation points, sorted in increasing order.

fval - The values of the interpolation points on all the grid knots: fval[i][j] = f(xval[i], yval[j]).

Returns:

a function which interpolates the dataset.

Throws:

NoDataException - if any of the arrays has zero length.

DimensionMismatchException - if the array lengths are inconsistent.

NonMonotonicSequenceException - if the array is not sorted.

NumberIsTooSmallException - if the number of points is too small for the order of the interpolation
