Surface Integration
I am needed something about calculation of surface integration using Gause integration method for a panel (like retangular panels) using high accuracy. This could be able to integrate for a given function and local coordinate, the output of intergal could be obtained. If you know some references or separate subroutine, please tell me to find it. Thanks!

Re: Surface Integration
(1). Have you looked into college Calculus or Advanced Calculus books ?

Re: Surface Integration
I am looking something as residual coefficients that give accurate value over the surface, not simple one. I have many subroutine to do that, now looking n=200, means the number of w(k)and s(k) by more than 200 coef.

Re: Surface Integration
You didn't mention whether the functions are singular or regular! Anyway, there are a number of good integration routines at www.netlib.org
