        public BilinearInterpolator()
        Empty constructor.

        This constructor is not strictly necessary, but it prevents spurious javadoc warnings with JDK 18 and later.

      • interpolate

        public BilinearInterpolatingFunction interpolate​(double[] xval,
                                                         double[] yval,
                                                         double[][] fval)
                                                  throws MathIllegalArgumentException
        Compute an interpolating function for the dataset.
        Specified by:
        interpolate in interface BivariateGridInterpolator
        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:
        MathIllegalArgumentException - if any of the arrays has zero length.
