• 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
