| Abstract: | As for the interpolation problem of two-variate cubic spline function, I advancemethod for computing interpolation coefficient, and give formulae for computingthe derivative, indefinite integral and definite integral by the spline function. I usethe two-variate cubic spline function to compute the vertical second derivative andupward continuation of gravity anomaly on geology model. Comparison betweenmodel trial values and theoretical values shows that the method is accurate and convenient. |
