Computes an interpolating function for the data set.

Specified by:

interpolate in interface BivariateRealGridInterpolator

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 data set.

Throws:

MathException - if arguments violate assumptions made by the interpolation algorithm.

java.lang.IllegalArgumentException
