public BicubicSplineInterpolatingFunction interpolate(double[] xval, double[] yval, double[][] fval) throws MathException, IllegalArgumentException Computes an interpolating function for the data set.- Specified by:
interpolate
in interfaceBivariateRealGridInterpolator
- 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.IllegalArgumentException
