Method Detail

interpolate

BivariateFunction interpolate(double[] xval,
                              double[] yval,
                              double[][] fval)
                              throws NoDataException,
                                     DimensionMismatchException,
                                     NonMonotonicSequenceException,
                                     NumberIsTooSmallException
Compute an interpolating function for the dataset.

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
