public interface BivariateGridInterpolator

Interface representing a bivariate real interpolating function where the sample points must be specified on a regular grid.

Method Summary

Modifier and Type Method Description

BivariateFunction interpolate(double[] xval, double[] yval, double[][] fval)
Compute an interpolating function for the dataset.

Method Details
- interpolate
  
  BivariateFunction interpolate(double[] xval, double[] yval, double[][] fval) throws NoDataException, DimensionMismatchException, NonMonotonicSequenceException, NumberIsTooSmallException
  
  Compute an interpolating function for the dataset.
  
  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
