      @Deprecated
      public class SmoothingPolynomialBicubicSplineInterpolator
      extends BicubicSplineInterpolator

  Generates a bicubic interpolation function. Prior to generating the interpolating function, the input is smoothed using polynomial fitting.
  Since:

      Deprecated.
      Compute an interpolating function for the dataset.
      Specified by:
        `interpolate` in interface `BivariateGridInterpolator`
      Overrides:
        `interpolate` in class `BicubicSplineInterpolator`
      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.
