interpolate
public PiecewiseBicubicSplineInterpolatingFunction interpolate(double[] xval, double[] yval, double[][] fval) throws DimensionMismatchException, NullArgumentException, NoDataException, NonMonotonicSequenceException
Compute an interpolating function for the dataset.- Specified by:
interpolatein interfaceBivariateGridInterpolator- 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:
DimensionMismatchException- if the array lengths are inconsistent.NoDataException- if any of the arrays has zero length.NonMonotonicSequenceException- if the array is not sorted.NullArgumentException
