Doc from org.apache.commons.math3.analysis.interpolation.BivariateGridInterpolator.interpolate.

Compute an interpolating function for the dataset.

Parameters
xval:double[]

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

yval:double[]

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

fval:double[][]

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

Returns:PiecewiseBicubicSplineInterpolatingFunction

a function which interpolates the dataset.

Exceptions
DimensionMismatchException:
if the array lengths are inconsistent.
NoDataException:
if any of the arrays has zero length.
NonMonotonicSequenceException:
if the array is not sorted.
