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
