      • interpolate

        TrivariateFunction interpolate​(double[] xval,
                                       double[] yval,
                                       double[] zval,
                                       double[][][] fval)
                                throws MathIllegalArgumentException
        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.
        zval - All the z-coordinates of the interpolation points, sorted in increasing order.
        fval - the values of the interpolation points on all the grid knots: fval[i][j][k] = f(xval[i], yval[j], zval[k]).
        Returns:
        a function that interpolates the data set.
        Throws:
        MathIllegalArgumentException - if any of the arrays has zero length.
        MathIllegalArgumentException - if the array lengths are inconsistent.
        MathIllegalArgumentException - if arrays are not sorted
        MathIllegalArgumentException - if the number of points is too small for the order of the interpolation
