                                      NoDataException,
                                      NonMonotonicSequenceException

  Parameters:

  x - Sample values of the x-coordinate, in increasing order.

  y - Sample values of the y-coordinate, in increasing order.

  f - Values of the function on every grid point.

  dFdX - Values of the partial derivative of function with respect to x on every grid point.

  dFdY - Values of the partial derivative of function with respect to y on every grid point.

  d2FdXdY - Values of the cross partial derivative of function on every grid point.

  Throws:

  DimensionMismatchException - if the various arrays do not contain the expected number of elements.

  NonMonotonicSequenceException - if x or y are not strictly increasing.

  NoDataException - if any of the arrays has zero length.

Method Detail

• value

  public double value(double x,
             double y)
               throws OutOfRangeException

  Compute the value for the function.

  Specified by:

  value in interface BivariateFunction

  Parameters:

  x - Abscissa for which the function value should be computed.

  y - Ordinate for which the function value should be computed.

  Returns:

  the value.

  Throws:

  OutOfRangeException

• isValidPoint

  public boolean isValidPoint(double x,
                     double y)

  Indicates whether a point is within the interpolation range.

  Parameters:

  x - First coordinate.

  y - Second coordinate.

  Returns:

  true if (x, y) is a valid point.
