• Numerical double integrations are very laborious even for a high speed computer in terms of CPU-time. Furthermore, if the integrand is composed of a product of several functions, more CPU-time is necessary to make the integrand a single function owing to the multiplication of functions. In this paper. we formulate the double integration by which both the multiplication of three functions (φ(x),ζ(x,y) and ψ(y)) and the integration are executed at a time. The formulation is accomplisbed with the use of bicubic spline functions.
