interpolate
public BicubicSplineInterpolatingFunction interpolate(double[] xval, double[] yval, double[][] fval) throws NoDataException, DimensionMismatchException, NonMonotonicSequenceException, NumberIsTooSmallException
Deprecated.Compute an interpolating function for the dataset.- Specified by:
interpolate
in 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:
NoDataException
- if any of the arrays has zero length.DimensionMismatchException
- if the array lengths are inconsistent.NonMonotonicSequenceException
- if the array is not sorted.NumberIsTooSmallException
- if the number of points is too small for the order of the interpolation
