Method Details

interpolate

public PiecewiseBicubicSplineInterpolatingFunction interpolate(double[] xval,
 double[] yval,
 double[][] fval)
                                                        throws MathIllegalArgumentException,
NullArgumentException

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:

MathIllegalArgumentException - if any of the arrays has zero length.

MathIllegalArgumentException - if the array lengths are inconsistent.

MathIllegalArgumentException - if the array is not sorted.

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

NullArgumentException
